Log all errors at handling point with contextual information (#321)
* feat(log): log all errors at handling point with context

This change ensures all errors are logged at the point where they are
handled, including contextual information such as operations and
logical stack traces.

Key changes:
- Added `StackTrace` and `FormatStackTrace` to `pkg/log/errors.go`.
- Enhanced `Logger.log` in `pkg/log/log.go` to automatically extract
  and log `op` and `stack` keys when an error is passed in keyvals.
- Updated CLI logging and output helpers to support structured logging.
- Updated CLI fatal error handlers to log errors before exiting.
- Audited and updated error logging in MCP service (tool handlers and
  TCP transport), CLI background services (signal and health), and
  Agentic task handlers.

- Removed unused `fmt` import in `pkg/cli/runtime.go`.
- Fixed CI failure in `auto-merge` workflow by providing explicit
  repository context to the GitHub CLI.

* feat(log): address PR feedback and improve error context extraction

Addressed feedback from PR review:
- Improved `Fatalf` and other fatal functions in `pkg/cli/errors.go` to
  use structured logging for the formatted message.
- Added direct unit tests for `StackTrace` and `FormatStackTrace` in
  `pkg/log/errors_test.go`, covering edge cases like plain errors,
  nil errors, and mixed error chains.
- Optimized the automatic context extraction loop in `pkg/log/log.go`
  by capturing the original length of keyvals.
- Fixed a bug in `StackTrace` where operations were duplicated when
  the error chain included non-`*log.Err` errors.
- Fixed formatting and unused imports from previous commits.

* fix: address code review comments

- Simplify Fatalf logging by removing redundant format parameter
  (the formatted message is already logged as "msg")
- Tests for StackTrace/FormatStackTrace edge cases already exist
- Loop optimization in pkg/log/log.go already implemented
