david raistrick d83d1383c0 refactor: single-source combat logic (App handlers call shared, slot model)
App.js no longer inlines combat logic. All handlers delegate to @ttrpg/shared:
startEncounter, nextTurn, togglePause, endEncounter, addParticipant(s),
updateParticipant, removeParticipant, toggleParticipantActive, applyHpChange,
deathSave, toggleCondition, reorderParticipants. ONE code path for UI.

shared/turn.js aligned to slot model (docs/INITIATIVE_ORDERING.md):
- addParticipant: splice into slot by initiative (no sort)
- updateParticipant: re-slot on initiative change (no sort)
- reorderParticipants: same-init drag only (cross-init blocked)
- applyHpChange: death flips isActive=false (matches App), revive reactivates

No renames, no API changes. Shared func signatures unchanged.

Tests updated to match unified behavior:
- dead-skip: death deactivates (was FEAT-1 stays active)
- characterization: death deactivates + revive reactivates
- reorder/invariant: cross-init drag blocked, same-init allowed

Both suites green: shared 91/91, App 77/77, 0 warnings.
