ToolCall.Name and .Arguments are json:"-" (runtime-only), so after chat
history round-trips through the session store only ToolCall.Function
survives. The anthropic-messages and anthropic (SDK) providers emitted
tool_use blocks from tc.Name alone, silently skipping every historical
tool call while still emitting the matching tool_result — orphaned
tool_results 400 at the API ("unexpected tool_use_id found in
tool_result blocks"), killing every turn on agents with tool history.
Fall back to Function.Name / json-parsed Function.Arguments (the same
pattern the bedrock and openai_compat providers already use), and cover
the deserialized-history shape with table tests in both providers.

* feat(auth): add Anthropic OAuth setup-token login flow
Add support for Anthropic's OAuth-based setup tokens (sk-ant-oat01-*)
as an alternative to API keys. This includes:
- New `--setup-token` flag on `auth login` command
- Interactive login menu for Anthropic (setup token vs API key)
- Setup token validation and credential storage with oauth auth method
- Usage endpoint integration to show 5h/7d utilization in `auth status`
- Streaming support for OAuth tokens (required by Anthropic API)
- Model ID normalization (dots to hyphens) for API compatibility
- Remove .env.example (secrets should not be templated)

Replace all claude-sonnet-4 references with claude-sonnet-4.6 across
codebase including documentation, tests, and configuration examples.

Phase 1: centralize protocol message/tool/response types in protocoltypes and keep compatibility aliases in providers and protocol packages.
Phase 1: preserve HTTPProvider constructor compatibility and route Anthropic api_base through factory auth/provider constructors with base URL normalization.
Phase 2: expand provider routing/auth tests (deepseek/nvidia/shengsuanyun, codex/claude oauth/codex-cli) and add openai_compat + anthropic coverage for proxy transport, model normalization, numeric option coercion, token-source refresh, and base URL behavior.
Phase 3: apply gofmt and validate with Dockerized tests (go test ./pkg/providers/... ./pkg/migrate and go test ./...).
