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. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com> * 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 --------- Co-authored-by: Claude Sonnet 4.5 <noreply@anthropic.com>

+ * Integration Test: Hook Execution Environments
+ *
+ * Tests that hooks can execute successfully in various shell environments,

+ *
+ * Prevents regression of Issue #264: "Plugin hooks fail with fish shell
