Module daemon 

sqry daemon subcommand handlers.

Provides lifecycle management for the sqryd daemon from the sqry CLI:

• sqry daemon start – resolve sqryd binary, exec sqryd start --detach.
• sqry daemon stop – connect via [DaemonClient], send daemon/stop, poll socket gone.
• sqry daemon status – connect via [DaemonClient], send daemon/status, render.
• sqry daemon logs – tail / follow the daemon log file.

Additionally exposes try_auto_start_daemon for future Task 13 wiring into query commands via the SQRY_DAEMON_AUTO_START=1 opt-in environment variable.

Tokio runtime

The stop and status subcommands need async I/O for [DaemonClient]. A current_thread runtime is created inside each handler — tokio is already a transitive dependency of sqry-cli via sqry-lsp.

Platform notes

try_connect_sync uses std::os::unix::net::UnixStream on Unix and a named-pipe existence probe on Windows so callers can check reachability without spinning up a Tokio runtime.

Functions

format_uptime

Format an uptime in seconds as "Xd Yh Zm" (or shorter when leading units are zero).

human_bytes

Format a byte count as a human-readable string (B / KB / MB / GB / TB).

run

Dispatch a sqry daemon subcommand.

tail_follow

Print the last initial_lines lines from path, then follow the file for new content using notify::RecommendedWatcher.

tail_last_n

Print the last n lines from path to stdout.

try_auto_start_daemon

Check whether the daemon auto-start opt-in is active, and if so, try to start the daemon.

try_connect_sync

Synchronously probe whether the daemon socket is reachable.
