Fix undo/redo forward-state restore, harden test infra, skip-guard

Root cause: mutation writers stored oldValues only. Redo rebuilt from
current state via derived logic — wrong order, wrong content, or no-op.
Undo patched fields in place but ignored roster/array order changes.

Writers now store forward arrays (shared/turn.js):
- addParticipant: newTurnOrderIds, newCurrentTurnParticipantId
- removeParticipant: newTurnOrderIds, newCurrentTurnParticipantId
- updateParticipant: oldTurnOrderIds + newTurnOrderIds (initiative re-slot)
- reorderParticipants: newParticipants + newTurnOrderIds
- damage/heal/deathSave/stabilize/revive/deactivate_dead_monster:
  oldValues + newValues both capture full death state incl conditions

expandUndo redo uses stored forward state instead of deriving:
- add/remove: order via newTurnOrderIds
- update: initiative change re-orders both directions
- reorder: re-applies newParticipants
- death ops: restore via newValues (was HP-only, dropped status/conditions)

Missing expandUndo cases added: stabilize, revive, deactivate_dead_monster
(were default:null -> undo no-op).

Test infra (shared/tests/_helpers.js):
- Mock storage undo() real now: applies patch + flips undone flag (was no-op)
- addDoc persists log entries, getCollection returns them
- undoLast/redoLast harness helpers exercise real mechanism
- Undo tests assert against actual persisted doc, not expandUndo output

turn.undo.test.js rewritten: every op tested as undo->deepEqual before,
redo->deepEqual after-op (12 cases). Was undo-only, redo untested.
turn.deathsave.undo.test.js added: 11 death-path roundtrips.

Dead code removed:
- round-trip.test.js: skipped suite testing deleted replay-from-logs.js
  (5 skipped tests rotting). Coverage gap acknowledged in TODO.

Skip-guard added (scripts/run-tests.sh): pre-flight grep refuses to run
if any .skip/xdescribe/xit found in test dirs. No CI; this is the gate.
