v6.5.56 (#12)

* feat(api): add comprehensive ampcode management endpoints

Add new REST API endpoints under /v0/management/ampcode for managing
ampcode configuration including upstream URL, API key, localhost
restriction, model mappings, and force model mappings settings.

- Move force-model-mappings from config_basic to config_lists
- Add GET/PUT/PATCH/DELETE endpoints for all ampcode settings
- Support model mapping CRUD with upsert (PATCH) capability
- Add comprehensive test coverage for all ampcode endpoints

* refactor(api): simplify request body parsing in ampcode handlers

* feat(logging): add upstream API request/response capture to streaming logs

* style(logging): remove redundant separator line from response section

* feat(antigravity): enforce thinking budget limits for Claude models

* refactor(logging): remove unused variable in `ensureAttempt` and redundant function call
