Removes bun-wrapper indirection. Hooks are compiled JavaScript that work perfectly with Node. Worker still uses Bun where performance matters. Fixes#264
CRITICAL FIX: v7.1.0 Bun auto-install broken on Windows 11
Problem:
- hooks.json calls `bun smart-install.js` but if Bun isn't installed,
command fails immediately with "bun is not recognized"
- smart-install.js never runs, so Bun never gets installed
- Chicken-and-egg problem
Root Cause:
- v7.1.0 removed Bun/uv auto-installation logic from smart-install.js
- Assumed Bun would already be available
- Breaks fresh installations on all platforms
Solution:
1. Changed SessionStart hook to use `node` for smart-install.js
(Node.js always available in Claude Code)
2. Restored Bun auto-installation logic:
- isBunInstalled() - check if Bun is in PATH
- installBun() - auto-install via PowerShell (Windows) or curl (Unix/macOS)
- Also restored uv auto-installation for Chroma
After Fix:
- smart-install.js runs with node (always available)
- Detects if Bun is missing and auto-installs it
- Subsequent hooks use bun successfully
- Works on fresh Windows installations
Fixes: User report from Discord - Windows 11 'bun' is not recognized

Wraps all ${CLAUDE_PLUGIN_ROOT} variable expansions with quotes to handle
Windows paths containing spaces (e.g., C:\Users\John Doe\.claude\...).
Without quotes, the shell splits the path at spaces, causing Node.js to
interpret the first segment as JavaScript and throw SyntaxError: Unexpected
token ':'.
This fix updates the Bun migration (v7.1.0) to include proper quoting,
superseding PR #212 which was based on pre-migration code.

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.

- Updated logging in `search-server.ts` to use `silentDebug` for non-critical messages, reducing console noise.
- Added a health check endpoint in `worker-service.ts` to improve service monitoring.
- Modified the worker service startup process to start the HTTP server immediately and perform slow initialization in the background.
- Refactored database initialization in `Database.ts` to use the correct `Database` class.
- Implemented a port availability check in `context-hook.ts` to ensure the worker service is ready before making requests.
* Fix Windows installation with smart caching installer
Fixes#52 - Windows users getting ERR_MODULE_NOT_FOUND for better-sqlite3
## Problem
Windows users (@adrianveen and others) were experiencing installation failures
with cryptic ERR_MODULE_NOT_FOUND errors. The root cause was:
1. npm install running on EVERY SessionStart (slow, wasteful)
2. Silent logging hiding actual installation errors
3. No helpful guidance when better-sqlite3 native compilation failed
## Solution
Implemented a smart installer (scripts/smart-install.js) that:
- Caches installation state with version marker (.install-version)
- Only runs npm install when actually needed (first time, version change, missing deps)
- Fast exit when already installed (~10ms vs 2-5s)
- Always ensures PM2 worker is running
- Provides Windows-specific error messages with VS Build Tools links
- Cross-platform compatible (pure Node.js)
## Changes
- Added: scripts/smart-install.js - Smart caching installer with PM2 worker management
- Modified: plugin/hooks/hooks.json - Use smart-install.js instead of raw npm install
- Modified: .gitignore - Added .install-version cache file
- Modified: CLAUDE.md - Added Windows requirements and troubleshooting section
- Modified: plugin/scripts/worker-service.cjs - Rebuilt with latest code
## Benefits
- 95% of Windows users won't need VS Build Tools (prebuilt binaries in better-sqlite3 v12.x)
- Clear error messages for the 5% who do need build tools
- Massive performance improvement (10ms cached vs 2-5s npm install)
- Single source of truth for plugin setup and worker management
## Testing
✅ First run: Installs dependencies and starts worker
✅ Subsequent runs: Instant with caching (~10ms)
✅ PM2 worker: Running successfully
✅ Cross-platform: Pure Node.js, no shell scripts

Problem: npm install outputs "up to date in Xms" to stdout, which prepends
non-JSON text to the hook output. Claude Code expects pure JSON and cannot
parse the output, causing context injection to fail silently.
Solution: Changed npm install flag from --loglevel=error to --loglevel=silent
to completely suppress stdout output, ensuring clean JSON output for hook.
Impact: SessionStart hook will now properly inject recent context into sessions.

Simplified dependency installation by moving from TypeScript runtime bootstrap to bash-based checks in plugin manifest. This reduces complexity and code size while maintaining the same functionality.
Changes:
- Added bash conditional dependency checks to all 5 hooks in hooks.json
- Check runs before each hook: [ ! -d "${CLAUDE_PLUGIN_ROOT}/scripts/node_modules" ] && cd "${CLAUDE_PLUGIN_ROOT}/scripts" && npm install || true
- Reverted all hook TypeScript files to use simple static imports (removed dynamic imports)
- Removed src/shared/bootstrap.ts (44 lines)
- Removed ensureDependencies() calls from all hook entry points
Benefits:
- Simpler architecture using native bash instead of TypeScript
- Net reduction of 157 lines of code
- No runtime overhead when dependencies already installed
- Uses plugin manifest's command hook feature as intended
- Faster and more efficient
