Added criterion benchmarks and optimized flatten_tool_result_content:
- Added criterion dev-dependency and request_building benchmark suite
- Optimized flatten_tool_result_content to pre-allocate capacity and avoid
intermediate Vec construction (was collecting to Vec then joining)
- Made key functions public for benchmarking: translate_message,
build_chat_completion_request, flatten_tool_result_content,
is_reasoning_model, model_rejects_is_error_field
Benchmark results:
- flatten_tool_result_content/single_text: ~17ns
- translate_message/text_only: ~200ns
- build_chat_completion_request/10 messages: ~16.4µs
- is_reasoning_model detection: ~26-42ns
All 119 unit tests and 29 integration tests pass.
cargo clippy passes

This adds an end-to-end OAuth PKCE login/logout path to the Rust CLI,
persists OAuth credentials under the config home, and teaches the
API client to use persisted bearer credentials with refresh support when
env-based API credentials are absent.
Constraint: Reuse existing runtime OAuth primitives and keep browser/callback orchestration in the CLI
Constraint: Preserve auth precedence as API key, then auth-token env, then persisted OAuth credentials
Rejected: Put browser launch and token exchange entirely in runtime | caused boundary creep across shared crates
Rejected: Duplicate credential parsing in CLI and api | increased drift and refresh inconsistency
Confidence: medium
Scope-risk: moderate
Reversibility: clean
Directive: Keep logout non-destructive to unrelated credentials.json fields and do not silently fall back to stale expired tokens
Tested: cargo fmt; cargo clippy --workspace --all-targets -- -D warnings; cargo test
Not-tested: Manual live Anthropic OAuth browser flow against real authorize/token endpoints
