Previously skipped Windows PM2 cleanup based on assumption that PM2
wasn't used on Windows. However, this left potential orphaned processes.
Changes:
- Remove platform check (process.platform !== 'win32')
- Run PM2 cleanup on Mac/Linux/Windows consistently
- Create .pm2-migrated marker on all platforms
- Update documentation to reflect cross-platform behavior
Rationale:
- Quality migration should clean up ALL orphaned processes
- Error handling (try/catch) already makes this safe
- Even if PM2 had Windows issues, cleanup won't hurt
- Consistent behavior across platforms is better UX
Impact:
- Windows users will get PM2 cleanup on first hook trigger
- Marker file now created on Windows (prevents repeated attempts)
- No breaking changes (errors caught and ignored)

- Enhanced logging functionality in user-message-hook.js to include better formatting and error handling.
- Updated worker-utils.ts to escape single quotes in PowerShell commands and added checks for global PM2 installation.
- Improved readability and maintainability of the code by restructuring and clarifying variable names.
**Problem:**
Worker service crashed on startup with:
TypeError: Cannot read properties of undefined (reading 'get')
at new Wd (.../worker-service.cjs:52:131469)
**Root Cause:**
Circular dependency between SettingsDefaultsManager and logger:
1. SettingsDefaultsManager imports logger
2. logger imports SettingsDefaultsManager
3. logger constructor calls SettingsDefaultsManager.get() at init time
4. When CommonJS resolves the cycle, SettingsDefaultsManager is undefined
**Solution:**
Break the circular dependency by making logger lazy-load its configuration:
- Change logger.level from initialized in constructor to lazy-loaded
- Add getLevel() method that loads on first access
- Update all level checks to use getLevel()
This allows SettingsDefaultsManager to import logger without triggering
the circular dependency, since logger no longer accesses SettingsDefaultsManager
during module initialization.

This PR addresses issue #193 affecting Windows installations of claude-mem.
## Bug 1: Missing ecosystem.config.cjs in packaged plugin
**Problem**: The ecosystem.config.cjs file was not included in the plugin
package, causing PM2 to fail when trying to start the worker from cache.
**Fix**: Added `plugin/ecosystem.config.cjs` with correct path for packaged
structure (`./scripts/worker-service.cjs` instead of `./plugin/scripts/`).
## Bug 2: Incorrect MCP Server Path (src/services/worker-service.ts)
**Problem**: Path `__dirname, '..', '..', 'plugin', 'scripts', 'mcp-server.cjs'`
only worked in dev structure, failed in packaged plugin.
**Error produced**:
```
Error: Cannot find module 'C:\Users\...\claude-mem\plugin\scripts\mcp-server.cjs'
[ERROR] [SYSTEM] Background initialization failed MCP error -32000: Connection closed
```
**Fix**: Changed to `path.join(__dirname, 'mcp-server.cjs')` since mcp-server.cjs
is in the same directory as worker-service.cjs after bundling.
## Bug 3: Missing smart-install.js in plugin package
**Problem**: smart-install.js was referenced in hooks.json but not included
in the plugin/ directory for cache deployment.
**Fix**: Added `plugin/scripts/smart-install.js` that uses `createRequire()`
to resolve modules from MARKETPLACE_ROOT.
## Bug 4: hooks.json incorrect path
**Problem**: Referenced `/../scripts/smart-install.js` but CLAUDE_PLUGIN_ROOT
points to the plugin/ directory.
**Fix**: Changed to `/scripts/smart-install.js`.
## Bug 5: Windows Worker Startup - Visible Console Windows
**Problem**: PM2 ignores windowsHide option on Windows, opening visible
console windows when starting the worker service.
**Fix**: Use PowerShell `Start-Process -WindowStyle Hidden` on Windows while
keeping PM2 for Unix systems (src/shared/worker-utils.ts).
## Additional Improvements
- Increased worker startup timeouts for Windows (500ms health check, 1000ms
wait between retries, 15 retries = 15s total vs previous 5s)
- Added `windowsHide: true` to root ecosystem.config.cjs for PM2
## Note on Assertion Failure
The Windows libuv assertion failure `!(handle->flags & UV_HANDLE_CLOSING)`
at `src\win\async.c:76` is a known upstream issue in Claude Code (Issue #7579),
triggered by fetch() calls on Windows. This is NOT caused by worker spawning
and cannot be fixed in claude-mem.
Tested on Windows 11 with Node.js v24.

- Introduced SettingsDefaultsManager to centralize default settings and loading logic.
- Updated context-generator, SDKAgent, SettingsRoutes, and worker-utils to utilize the new manager for loading settings.

* fix: Hide console window on Windows when spawning child processes
Add windowsHide: true to spawnSync and execSync calls to prevent
empty console windows from appearing on Windows when hooks execute.
Fixes two spawn points:
- worker-utils.ts: PM2 spawn when starting worker service
- user-message-hook.ts: Node spawn for context display
Reference: https://nodejs.org/api/child_process.html (windowsHide option)

* fix: Add windowsHide to remaining execSync calls for complete Windows console window hiding
This completes the Windows console window fix by adding `windowsHide: true` to all remaining `execSync` calls:
- src/services/worker-service.ts:220 - pgrep command for orphaned process detection
- src/services/worker-service.ts:226 - pkill command for process cleanup
- src/services/worker/SDKAgent.ts:414 - where/which claude command for finding executable
These operations are less frequent than the user-prompt hook, but should still avoid spawning console windows on Windows for a complete fix.
