Closes Phase 19's UI surface. The inspector dispatches on the
selection variant: local / other groups render class, count, the
four tech levels, mass, cargo (type + amount when loaded),
location (planet name on-orbit, from/to/distance in hyperspace),
and — for local groups only — fleet membership + state. Incoming
groups surface origin / destination / distance / speed and the
inline ETA = ceil(distance / speed); zero speed collapses to the
designer's existing "—" placeholder. Unidentified groups render
just the (x, y) coordinates and the no-data hint, mirroring the
unidentified planet treatment.
Layout / inspector-tab plumbing:
- inspector-tab.svelte derives selectedShipGroup against the
rendered report and mounts <ShipGroup /> when the planet
branch doesn't match. Stale refs (an index that no longer
resolves after a turn refresh) collapse cleanly to the empty
state.
- +layout.svelte mounts <ShipGroupSheet /> alongside the
existing planet sheet on mobile; both share the
`effectiveTool === "map"` guard and clear-on-close.
i18n: en + ru both grow ~30 keys under
`game.inspector.ship_group.*`. Adding a key to one without the
other is a TS error (TranslationKey is `keyof typeof en`), so the
Russian mirror stays mandatory.
Tests:
- inspector-ship-group.test.ts exercises every variant —
on-planet local, in-hyperspace local, cargo-loaded local,
foreign, incoming with ETA, incoming with zero speed,
unidentified, plus the missing-planet `#NN` fallback.
- tests/e2e/inspector-ship-group.spec.ts is a smoke spec that
drives the DEV-only synthetic-report loader from /lobby
through navigation to /games/synthetic-XXX/map.
