WithMaxMessageLength(4000) already ensures msg.Content ≤ 4000 chars
before reaching Send(), making the SplitMessage call redundant.
The HTML expansion safety net (re-split when >4096 after conversion)
is still preserved.

* feat(commands): Session management [Phase 1/2] command centralization and registration
* docs: add design for command registry post-review fixes
Documents the architecture decisions for fixing 5 Important issues
from code review: SubCommand pattern, Deps struct, command-group files,
Executor caching, and Telegram registration dedup.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* feat(commands): add SubCommand type and EffectiveUsage method
Introduce SubCommand struct for declaring sub-commands structurally
within a parent command Definition. The EffectiveUsage() method
auto-generates usage strings from sub-command names and args,
preventing drift between help text and actual handler behavior.

* feat(commands): add sub-command routing to Executor
Uses Registry.Lookup for O(1) command dispatch instead of iterating
all definitions. Definitions with SubCommands are routed to matching
sub-command handlers. Missing or unknown sub-commands reply with
auto-generated usage.

* refactor(commands): split into command-group files with Deps injection
Extract show/list/start/help into individual cmd_*.go files.
Replace config.Config parameter with Deps struct for runtime data.
Restore /show agents and /list agents sub-commands.
Use EffectiveUsage for auto-generated help text.
Bridge external callers (agent/loop.go, telegram.go) with Deps wrapper
until Task 5 fully wires the Deps fields.

* refactor(commands): replace Deps with per-request Runtime
Separate stateless Registry (cached on AgentLoop) from per-request
Runtime (passed to handlers at execution time). This enables future
session management features to inject per-request context without
modifying the command registry.
- Rename Deps → Runtime, move to runtime.go
- Change Handler signature: func(ctx, req) error → func(ctx, req, rt *Runtime) error
- NewExecutor now takes (registry, runtime) — executor is created per-request
- BuiltinDefinitions() no longer takes parameters (stateless)
- AgentLoop caches cmdRegistry, builds Runtime via buildRuntime()

Context-dependent commands that need a routed agent will report
"unavailable" through their nil-Runtime guards.

handlers reply "unavailable"
- Restore GetMyCommands + slices.Equal check before SetMyCommands to
avoid unnecessary Telegram API calls on restart

After re-splitting an oversized chunk, sub-chunks were sent without
verifying their HTML also fits under 4096 chars. Non-uniform HTML
expansion (e.g. a sub-chunk dense with bold/links) could still exceed
the limit. Use a queue that pushes sub-chunks back for re-validation
instead of sending them blindly.

The Manager splits at MaxMessageLength before calling Send(), and
Telegram's Send() was re-splitting at 4000 internally. Aligning the
channel-level limit to 4000 avoids that redundant second split while
preserving the safety margin for markdown-to-HTML expansion.

Address Copilot review feedback:
- Move resolveDiscordRefs(content) before the referenced message
concatenation to prevent message links in quoted replies from being
expanded twice.
- Add unit tests for channelRefRe and msgLinkRe regex patterns,
covering valid/invalid inputs and the 3-link cap.
Security fix: resolveDiscordRefs now takes a guildID parameter and
skips message links pointing to a different guild, preventing the bot
from leaking content across guilds.
Also uses s.State.Channel() cache before falling back to API calls
to reduce Discord API usage and rate limit risk.
- Guard against nil ReferencedMessage.Author to prevent panic
- Hoist regexp.MustCompile to package-level vars to avoid
re-compilation on every handleMessage call
- Both are defensive programming improvements
Add resolveDiscordRefs method that:
1. Resolves <#id> channel mentions to #channel-name by calling
the Discord API to fetch channel info
2. Expands Discord message links (up to 3) by fetching the linked
message content and appending it as '[linked message from User]: content'
Applied to both quoted/referenced messages and the main message
content for full context resolution.
When a user replies to a message in Discord, the bot now reads
m.ReferencedMessage and prepends its content to the incoming
message as '[quoted message from Username]: content'.
This gives the LLM full context of what message the user is
replying to, enabling meaningful follow-up conversations.

- Consolidate extractImageKey/extractFileKey/extractFileName into shared

- Remove stale "falls back to plain text" comment on Send
- Add empty ChatID validation in SendMedia to match Send
- Use messageID+fileKey as local filename to avoid write collisions
- Check allowlist before downloading inbound media to avoid wasted I/O
- Return errUnsupported consistently from all 32-bit stub methods
Upgrade the Feishu channel from basic text-only to full feature parity with
Telegram/Discord: interactive card messages with markdown rendering, message
editing (MessageEditor), placeholder messages (PlaceholderCapable), emoji
reactions (ReactionCapable), and inbound/outbound media support (MediaSender).
Also add @mention detection with lazy bot open_id discovery, group trigger
filtering with mention awareness, and multi-type inbound message parsing
(text, post, image, file, audio, video).
The previous dedupe map rotation logic completely cleared the map when it reached max size, causing an 'amnesia cliff' where immediately arriving duplicates of just-forgotten messages would be processed.
This change replaces that with a MessageDeduplicator struct that uses a circular queue (ring buffer) to track insertions. When the limit is reached, it only evicts the absolute oldest message from the map, completely resolving the cliff issue.
This also cleans up the WeCom Bot and App webhook handlers by encapsulating the mutex and map state.
When the dedupe map rotates, the previous logic entirely cleared the map, meaning the message that triggered the rotation was immediately forgotten and could be duplicated immediately.
This change seeds the new map with the current message to prevent that. Also adds a defensive nil check.
Match rotation semantics to prior behavior by fully resetting the dedupe map
once the size limit is exceeded, and add focused tests for duplicate detection
and boundary rotation behavior.
Centralize dedupe map access behind a mutex-safe helper and use it in both
WeCom bot and WeCom app channels to eliminate concurrent map access races while
preserving current dedupe behavior.
When markdownToTelegramHTML expands a chunk beyond 4096 chars (e.g.
**a** → <b>a</b>), re-split the markdown with a proportionally smaller
maxLen so each resulting HTML chunk fits within Telegram's limit.
Extract sendHTMLChunk helper to avoid duplicating the HTML-send +
plain-text-fallback logic.
Add test case for markdown-short-but-HTML-long scenario to verify
the re-splitting behavior.

* fix(tools): close resp.Body on retry cancel and cache http.Client instances
Fix resp.Body leak in DoRequestWithRetry where req.Body (request) was
incorrectly closed instead of resp.Body (response) on context cancel.
Cache http.Client on web search/fetch provider structs and channel
adapters (WeCom, LINE) to avoid per-call allocation overhead.
* fix(channels): preserve original http client timeouts for LINE and WeCom
Split LINE single 60s client into infoClient (10s) for bot info lookups
and apiClient (30s) for messaging API calls. Lower WeCom cached client
base timeout from 60s to 30s (matching uploadMedia), and ensure it is
always >= the configured ReplyTimeout so the per-request context
deadline remains the effective limit.
* refactor(tools): extract timeout consts and deduplicate WebFetchTool constructors
Address PR review feedback from xiaket:
- Define searchTimeout, perplexityTimeout, fetchTimeout, defaultMaxChars,
and maxRedirects as package-level consts instead of magic numbers.
- Remove misleading "No proxy" comment in NewWebFetchTool.
- Deduplicate NewWebFetchTool by delegating to NewWebFetchToolWithProxy.
* test(utils): add context cancellation test for DoRequestWithRetry
Verify that resp.Body is properly closed when the context is canceled
during retry sleep, covering the C8 resp.Body leak fix.
* fix(utils): close resp in test to satisfy bodyclose linter
* fix(utils): eliminate flakiness in context cancellation retry test
Synchronize cancellation using an onRoundTrip callback from the
transport wrapper instead of a timing-based context timeout. This
ensures the first client.Do completes before cancel fires, so
cancellation always hits during sleepWithCtx.

Cancel the constructor-created context before overwriting in Start()
to prevent the original cancel function from becoming unreachable.
Move len(processedMsgs) check inside the write lock to eliminate a
data race, and re-insert the current msgID after map reset to prevent
duplicate processing of the in-flight message.
Applies to both WeComBotChannel and WeComAppChannel.
The ctx field was only set in Start(), so tests calling handleMessageCallback
without Start() caused a nil pointer dereference in MessageBus.PublishInbound.
The HTTP request context is canceled as soon as the handler returns the
response, causing PublishInbound to fail with "context canceled" when
processMessage runs asynchronously in a goroutine. Use the channel's
long-lived context (c.ctx) instead.
- WhatsApp Start(): use deferred cleanup to nil out c.client/c.container
and disconnect/close resources on any error after struct fields are
assigned, preventing stale references and double-close in Stop()
- handleReasoning: treat bus.ErrBusClosed as an expected condition
(DEBUG level) alongside context timeout/cancel, avoiding WARN noise
during normal shutdown
- WhatsApp Send(): detect unpaired state (Store.ID == nil) and return
ErrTemporary instead of attempting to send while QR login is pending
- handleReasoning: check the returned error type (DeadlineExceeded /
Canceled) instead of ctx.Err() to decide log level, so pubCtx
timeouts on a full bus are correctly classified as expected
- Test: fill bus with a short-timeout loop instead of hardcoding the
buffer size (64), making the test resilient to buffer size changes
Move the stopping check and wg.Add(1) inside reconnectMu in
eventHandler, and set the stopping flag under the same lock in Stop().
This makes the two operations atomic with respect to each other,
preventing the race where:
1. eventHandler checks stopping (false)
2. Stop() sets stopping=true and enters wg.Wait() (wg is 0)
3. eventHandler calls wg.Add(1) → panic or goroutine leak
- Use c.runCtx for GetQRChannel so the QR producer is canceled on Stop()
- Add atomic stopping guard to prevent wg.Add/wg.Wait race in eventHandler
- Make Stop() context-aware: disconnect client before waiting, respect ctx deadline
- Reduce reasoning publish log noise: use debug level for expected ctx errors
- Add test for handleReasoning when outbound bus is full (timeout path)
- Move runCtx/runCancel creation before event handler registration and
QR loop so Stop() can cancel at any point during startup
- Replace blocking QR event loop in Start() with a background goroutine
that selects on runCtx.Done(), preventing Start() from hanging
indefinitely when waiting for QR scan
- Track all background goroutines (QR handler, reconnect) with
sync.WaitGroup; Stop() waits for them to finish before releasing
client/container resources
- Cancel runCtx on error paths in Start() to avoid leaked contexts
Fixes resource leak introduced in #655.
