- Updated quickstart links and clarified CLIProxyAPI support information.
Preserve Codex and XAI upstream message-too-big closes across the Responses WebSocket boundary while treating them as request-scoped errors. Prevent CPA reconnect and credential cooldown/fallback, scope close state to the active connection, retain terminal errors under backpressure, and ensure downstream disconnect cleanup cannot wait behind a blocked writer.
- Added `GetGJSONBytesNoCopy` in `internal/util` for safe, no-copy JSON parse operations leveraging `unsafe`.

- Added unit tests for behavior validation, including edge cases with empty input.
- Introduced `SetStringIfDifferent`, `SetBoolIfDifferent`, and similar helpers in `payload_helpers` to avoid unnecessary writes during JSON modifications.
- Simplified message patching in `kimi_executor` for reasoning and tool call adjustments.
- Updated all executors (Gemini, Codex, XAI, Antigravity, etc.) to use the new helpers, enhancing readability and potentially reducing overhead.
