Alex Newman 52d2f72a82 Standardize and enhance error handling across hooks and worker service (#295)
* Enhance error logging in hooks

- Added detailed error logging in context-hook, new-hook, save-hook, and summary-hook to capture status, project, port, and relevant session information on failures.
- Improved error messages thrown in save-hook and summary-hook to include specific context about the failure.

* Refactor migration logging to use console.log instead of console.error

- Updated SessionSearch and SessionStore classes to replace console.error with console.log for migration-related messages.
- Added notes in the documentation to clarify the use of console.log for migration messages due to the unavailability of the structured logger during constructor execution.

* Refactor SDKAgent and silent-debug utility to simplify error handling

- Updated SDKAgent to use direct defaults instead of happy_path_error__with_fallback for non-critical fields such as last_user_message, last_assistant_message, title, filesRead, filesModified, concepts, and summary.request.
- Enhanced silent-debug documentation to clarify appropriate use cases for happy_path_error__with_fallback, emphasizing its role in handling unexpected null/undefined values while discouraging its use for nullable fields with valid defaults.

* fix: correct happy_path_error__with_fallback usage to prevent false errors

Fixes false "Missing cwd" and "Missing transcript_path" errors that were
flooding silent.log even when values were present.

Root cause: happy_path_error__with_fallback was being called unconditionally
instead of only when the value was actually missing.

Pattern changed from:
  value: happy_path_error__with_fallback('Missing', {}, value || '')

To correct usage:
  value: value || happy_path_error__with_fallback('Missing', {}, '')

Fixed in:
- src/hooks/save-hook.ts (PostToolUse hook)
- src/hooks/summary-hook.ts (Stop hook)
- src/services/worker/http/routes/SessionRoutes.ts (2 instances)

Impact: Eliminates false error noise, making actual errors visible.

Addresses issue #260 - users were seeing "Missing cwd" errors despite
Claude Code correctly passing all required fields.

* Enhance error logging and handling across services

- Improved error messages in SessionStore to include project context when fetching boundary observations and timestamps.
- Updated ChromaSync error handling to provide more informative messages regarding client initialization failures, including the project context.
- Enhanced error logging in WorkerService to include the package path when reading version fails.
- Added detailed error logging in worker-utils to capture expected and running versions during health checks.
- Extended WorkerErrorMessageOptions to include actualError for more informative restart instructions.

* Refactor error handling in hooks to use standardized fetch error handler

- Introduced a new error handler `handleFetchError` in `shared/error-handler.ts` to standardize logging and user-facing error messages for fetch failures across hooks.
- Updated `context-hook.ts`, `new-hook.ts`, `save-hook.ts`, and `summary-hook.ts` to utilize the new error handler, improving consistency and maintainability.
- Removed redundant imports and error handling logic related to worker restart instructions from the hooks.

* feat: add comprehensive error handling tests for hooks and ChromaSync client
