Implement logging infrastructure for non-systemd platforms:
- Add src/logging.rs with syslog and file logging support
- New CLI flags: --syslog, --log-file, --log-file-daily
- Syslog uses libc directly with LOG_DAEMON facility
- File logging via tracing-appender with optional daily rotation
Update service scripts:
- OpenRC and FreeBSD rc.d now use --syslog by default
- Ensures logs are captured on platforms without journald
Default (stderr) behavior unchanged for systemd compatibility.
Log destination is selected at startup based on CLI flags.

Implement CLI subcommands for managing telemt as a daemon:
- `start [config.toml]` - Start as background daemon (implies --daemon)
- `stop` - Stop running daemon by sending SIGTERM
- `reload` - Reload configuration by sending SIGHUP
- `status` - Check if daemon is running via PID file
Subcommands use the PID file (default /var/run/telemt.pid) to locate
the running daemon. Stop command waits up to 10 seconds for graceful
shutdown. Status cleans up stale PID files automatically.
Updated help text with subcommand documentation and usage examples.
Exit codes follow Unix convention: 0 for success, 1 for not running
or error.

Implement core daemon infrastructure for running telemt as a background
service on Unix platforms (Linux, FreeBSD, etc.):
- Add src/daemon module with classic double-fork daemonization
- Implement flock-based PID file management to prevent duplicate instances
- Add privilege dropping (setuid/setgid) after socket binding
- New CLI flags: --daemon, --foreground, --pid-file, --run-as-user,
--run-as-group, --working-dir
Daemonization occurs before tokio runtime starts to ensure clean fork.
PID file uses exclusive locking to detect already-running instances.
Privilege dropping happens after bind_listeners() to allow binding
to privileged ports (< 1024) before switching to unprivileged user.

This commit adds support for configuring the data path via a
configuration file or command-line option. This may be useful
on systems without systemd, such as OpenWrt or Alpine Linux.
