2026-04-10	Fix known-hosts trust deadlock, host key stat, and optional nozstd build	Paul Buetow
	- stdout logger: release mutex while waiting on pause resume so prompt callbacks can log (fixes hang after trusting new hosts; known_hosts was written but Resume never ran). - known hosts callback: stop borrowing the SSH dial throttle channel (could block or interact badly with parallel handshakes). - host key path: use errors.Is(..., fs.ErrNotExist) for RootedPath.Stat wrapped errors; stat errors now fail fast instead of mis-read. - public key path: same ErrNotExist check for authorized_keys miss. - Build: optional DTAIL_NO_ZSTD=yes / nozstd tag for CGO-free builds; split zstd readers into tagged files. - Docs/examples: firewalld note for port 2222, log prune timer+script, SSHBindAddress note, dserver unit disabled-by-default comment; firewalld helper script example. - Regression test for stdout pause/mutex behavior.

2025-07-01	fix: resolve turbo mode race condition and improve TestDCat2	Paul Buetow
	- Fixed race condition in periodicTruncateCheck by using context cancellation - Added turbo mode support to TestDCat2 server configuration - Removed problematic wait for pending files in readCommand.Start - Fixed potential panic when truncate channel is closed while goroutine is running The test now properly enables turbo mode on both client and server, preventing the timeout issues that occurred when only the client had turbo mode enabled. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
