bug(daemon): bare `ccstatusline daemon` starts a foreground server instead of printing usage

[axisrow]

Bug

ccstatusline daemon with no subcommand starts the daemon as a foreground server instead of printing usage. Every other invalid/missing verb prints the usage line and exits:

usage: ccstatusline daemon [start|stop|status|restart|install|uninstall]

Repro

1. Run ccstatusline daemon (bare).
2. The process blocks in the foreground running the server (observed: the instance stayed alive ~2 minutes until manually stopped).
3. Expected: print the usage line and exit non-zero, same as ccstatusline daemon bogus does.

Notes

• Discovered during the dist rebuild smoke test (fork build 2.2.30.fork1, main 597f94c, post-feat(daemon): opt-in shared-mode install, status/recovery UX, benchmarks and acceptance gates (#19) #50).
• daemon stop / daemon status work as expected; only the bare invocation is affected.
• Low severity, good first issue: a single args.length === 0 guard next to the unknown-verb branch.
