feat(thressgame-coverage): Wave 2 (entity attrs + aura + RNG + marker factory)

Browse source 
- T6: 7 new entity attrs (EntityKind, MarkerKind, MarkerLifetime, MarkerOwner, MarkerLinks, RngSeed, RngStream) + registerAttrConsumer
- T7: aura compute admits markers via EntityKind discriminator (default-to-piece policy); +getEntityKind helper
- T8: 5 movement-replacement attrs (MovesAs, MovesAlsoAs, SlideMustBeMaxDistance, BlockAllExceptKing, KingExtraReach)
- T9: Mulberry32 PRNG (SeededRng) + deriveSeedFromGameId + engine.rng()/setRngSeed() with persistent RngStream advancement
- T10: engine.spawnMarker/removeMarker/getMarkersAtSquare with hardcoded priority table (portal-end<frozen-square<mine<...<blocked) + entity-id tiebreak

Tests: 1970 -> 2014 (+44). bun run check exit 0.

- Edit `packages/chess/src/schema.ts`: extend ChessAttrMap with `EntityKind: "piece" | "marker"`, `MarkerKind: "mine" | "pit" | "portal-end" | "frozen-square" | "treasure" | "death-square" | "tornado" | "blocked"`, `MarkerLifetime: { kind: "permanent" } | { kind: "moves"; expiresAtMove: number } | { kind: "one-shot" }`, `MarkerOwner: "white" | "black" | undefined`, `MarkerLinks: readonly EntityId[]`, `RngSeed: number`, `RngStream: number`
