## Changelog
### Performance Improvements
- **perf: make terminal creation cwd check async (#9)**
Replaced synchronous `fs.existsSync` with `fs.promises.access` in the terminal creation handler to prevent blocking the event loop.
Improves throughput under high load.
- **perf: optimize fuzzyMatchScore by avoiding redundant lowercasing (#8)**
Renamed `fuzzyMatchScore` to `fuzzyMatchScoreNormalized` and updated it to accept a pre-lowercased query, avoiding repeated string allocations.
Updated the call site in `searchFilesystemFiles`.
~25% search performance improvement on large datasets.
- **perf: use async file read in update-install handler (#7)**
Replaced `fs.readFileSync` with `await fs.promises.readFile` to avoid blocking the event loop.
**Benchmark (10k ops):**
- Sync: ~95ms (blocking)
- Async: ~1124ms (non-blocking)
Higher per-call overhead, but better server responsiveness.
- **perf(server): optimize mkdir endpoint with async fs (#6)**
Replaced `fs.mkdirSync` with `await fsPromises.mkdir` in `/api/fs/mkdir`.
Prevents event-loop blocking and improves concurrent performance.
**Result:** ~2× throughput improvement (100 concurrent requests).
- **perf: parallelize fs checks in validateProjectEntries (#4)**
Replaced serial `for...of` with `Promise.all + map`.
Reduced validation time for 500 projects from ~110ms to ~20ms (~5× speedup).
- **perf: cache getLoginShellPath result to avoid blocking event loop (#5)**
Cached `getLoginShellPath` result to avoid repeated `spawnSync` calls (~400ms each).
Subsequent calls reduced to <1ms.
---
### Server Fixes
- **fix(server): use async check for terminal restart endpoint (#3)**
Replaced `fs.existsSync` with `fs.promises.stat` in `/api/terminal/:sessionId/restart`.
Added directory validation for better robustness.
