Management CLI for the_grid — `grid watch` and companion commands for operating a grid station.

Changelog

0.2.0

• Breaking: StationLockService.acquire no longer takes a pgid parameter — the service now establishes the station's own process group itself (setsid-own-group before the lock write) and refuses via StationRefusal when the resolved pgid is not the station pid. Migration: drop the pgid: argument from acquire(...) call sites; if you were computing a group id to pass in, delete that code — the recorded pgid is now always the station's own, verified group.
• stop() gains a pgid-gated group signal: when the lock's recorded pgid matches the live process group, teardown signals the whole group; on mismatch it falls back loudly to the previous pid-scoped SIGTERM.
• New: establishStationProcessGroup (re-exported), with ProcessGroupController.resolvePgid as the single source of process-group identity; regression test boots from a non-leader parent and asserts the recorded group is the station's own tree.

• Initial tagged release (ADR-0003 tag-pattern version solving).
