Add IPC backoff/retries and safer disposal

Introduce exponential backoff, jitter and retry logic across IPC components to improve robustness and avoid tight retry loops; make disposal idempotent and add connection guards. Key changes:
- LauncherCoordinatorIpcServer / LauncherIpcServer: add backoff constants, ComputeBackoff(), consecutive error tracking and delayed retries with jitter.
- LanMountainDesktopIpcClient / LauncherIpcClient: add connect retry loops, timeouts, delayed retries, improved error logging, and use ArrayPool for buffered async writes; ensure proper cleanup on failures.
- PublicIpcHostService: add disposed flag, guard OnPeerConnected and Dispose, and clear connected peers on dispose.
- Add many auto-generated commit analysis docs under docs/auto_commit_md and new scripts for analyzing/generating commit docs.
These changes aim to make IPC connection handling more resilient and resource-safe.
