The !setup confirm path seeds the canonical player_meta row (commit
667f87f), but the auto-migration path (ensureDnDCharacterForCombat) writes
a confirmed dnd_character without touching the legacy layer. Commands that
trigger it — !rest, !cast, !abilities, !skills — derive the adventure char
via a bare loadAdvCharacter that is nil when player_meta is absent, and
autoBuildCharacter tolerates a nil char. So a brand-new player whose
first-ever adventure action is one of those gets a confirmed character with
no player_meta, which then fails every legacy-layer command (expeditions,
arena, world boss, town, duels) with "sql: no rows" — the same state
@camcast was found in.
Fix: ensurePlayerMetaSeed guarantees the seed row (+ tier-0 equipment)
exists at the fresh auto-migration point. Conditional on player_meta being
absent, so it's idempotent and never duplicates a legacy player's gear
(createAdvCharacter's equipment insert has no conflict guard).
Regression tests cover both the straggler repro (first-ever !rest seeds
player_meta + loads cleanly) and idempotency (no equipment duplication).
