1.1.9

- Completed the canonical state and world-map migration so gameplay, AI,
multiplayer, replay, persistence, and rendering share one immutable map and
one authoritative domain state without transitional command or map models.

- Versioned multiplayer compatibility explicitly and added a translated update
notice for clients that must wait for or install a compatible release.

- Fixed observed multiplayer movement so exact and visibility-safe coarse
movement remain ordered, animate once, and do not leak hidden path details.

- Made manual movement immediately available for fortified units and cancel
fortification when a route is chosen, while keeping movement targeting and
route reachability consistent after turn and snapshot reconciliation.

- Anchored excavation and artifact-transfer notifications above their unit or
city on the map instead of presenting them as detached HUD messages.

- Strengthened root coverage around web persistence composition, lobby map
capacity, movement and merchant HUD commands, cultural outcomes, map assets,
release notices, and AI trace diagnostics.
