v0.1.1 — Bug Fixes

Fixed: Session logs truncated on exit (close flush was fire-and-forget)

close() called flush() but never awaited it. Since flush() does async appendFile, the process could exit before the final batch wrote to disk — silently losing the tail of the session log.

• close() now returns Promise<void> and awaits flush()
• Added closeSync() using writeFileSync for signal handler paths (SIGTERM/SIGINT) where async isn't possible
• Updated all callers in proxy.ts to await close() or use closeSync() as appropriate

Fixed: False hallucination hints under concurrent requests

The hallucination heuristic used single scalar variables (lastResponseWasError, lastErrorMethod, lastErrorToolName). If the client sent requests A and B concurrently, interleaved responses would corrupt the state — the next client request could falsely trigger a hallucination hint.

• Replaced scalar state with an ordered list of recent server responses (recentResponses[])
• When a client request arrives, checks only the most recent server response for the error-then-different-tool pattern
• Correctly handles interleaved responses without false positives

Fixed: Synchronous disk space check blocking startup

createSessionLogger used execSync('df ...') to check available disk space. On slow disks or network mounts this could add visible latency to proxy startup.

• Replaced execSync + shell df command with fs.statfs() (async, native Node.js API)
• Cross-platform: works on Windows unlike the previous df-based approach
• No shell spawning overhead
