Adv 2.0 L5e: death state migration off AdvCharacter

Browse Source 
Eight player_meta columns: alive (default 1), dead_until,
death_reprieve_last, last_pardon_used (DATETIME), last_death_date,
grudge_location, death_source, death_location (TEXT).

DeathState struct + load/upsert/backfill/projection helpers. Dual-write
strategy switches: instead of per-site upserts, the dual-write rides
saveAdvCharacter itself (after the existing display_name dual-write).
Death-state mutation surface spans ~50 save sites; the saveAdvCharacter-
internal hook catches every one without scatter.

Backfill idempotent (only fills rows where every death field is still
default). Tests cover backfill, fallback, round-trip, and the
saveAdvCharacter dual-write.
