Error suggestions now include concrete CLI examples so users
(and robot-mode consumers) can act immediately without consulting
docs. For instance, ConfigNotFound now shows the expected path
and the exact command to run, TokenNotSet shows the export syntax,
and Ambiguous shows the -p flag with example project paths.
Also fixes the error code for Ambiguous errors: it now maps to
GitLabNotFound instead of InternalError, since the entity exists
but the user needs to disambiguate -- not an internal failure.

Improves core infrastructure with robot-friendly error output and
faster lock release for better sync behavior.
Error handling improvements (error.rs):
- ErrorCode::exit_code(): Unique exit codes per error type (1-13)
for programmatic error handling in scripts/agents
- GiError::suggestion(): Helpful hints for common error recovery
- GiError::to_robot_error(): Structured JSON error conversion
- RobotError/RobotErrorOutput: Serializable error types with code,
message, and optional suggestion fields
Lock improvements (lock.rs):
- Heartbeat thread now polls every 100ms for release flag, only
updating database heartbeat at full interval (5s default)
- Eliminates 5-10s delay after sync completion when waiting for
heartbeat thread to notice release
- Reduces lock hold time after operation completes
Database (db.rs):
- Bump expected schema version to 6 for MR migration
The exit code mapping enables shell scripts and CI/CD pipelines to
distinguish between configuration errors (2-4), GitLab API errors
(5-8), and database errors (9-11) for appropriate retry/alert logic.
