refactor(simulation): replace ad-hoc system ordering with TickPhase pipeline (#843)

10-phase linear pipeline: PreInput → Input → Movement → Simulation →
Economy → Storyteller → Snapshot → PostSnapshot → Knowledge → TickAdvance.

Each system assigned to exactly one phase via .in_set(TickPhase::X).
Cross-phase .after()/.before() eliminated — only intra-phase ordering
remains. Prevents schedule cycles by construction.

SimulationPlugin refactored into sub-plugins by domain:
  - InputPlugin (player actions, interactions, dialogue dispatch)
  - MovementPlugin (pathfinding, movement validation, spatial indexing)
  - SocialPlugin (conversations, sound, voice enrichment, follow state)
  - EconomyPlugin (tâtonnement tick, IPC query serving)
  - TimePlugin (chunk streaming, news ticker, tick advancement)

All other plugins (NPC, Knowledge, Perception, Storyteller, Settings,
Bridge) updated to use TickPhase assignments instead of cross-plugin
ordering constraints. BridgePlugin trimmed to bridge I/O concerns only.

Part A of #843. Parts B (multi-threaded executor) and C (background
workers) follow.
