- external list now accepts serial: and size: prefixes; desc: matches
serial too. Fixes docked-mode deadlock where Hyprland's synthetic
FALLBACK output (created when the built-in is disabled by a stale
docked config) was treated as a real external monitor, leaving the
daemon stuck in docked after undocking.
- modes name resolution gains serial: prefix (resolveSerial).
- add -log-level flag for observability.
- add unit tests for external matching and name resolution.
- update README and example config.
Add WriteConfig/Prepare backend methods (real for Hyprland, no-op for
Sway), -apply/-prepare/-no-reload CLI flags, ExecStartPre cleanup and
suspend systemd hooks so a stale docked config can never leave the
built-in display disabled after resume.
