Wire movement narration through the pipeline

[dkirby-ms]

Summary

The movement narration type is defined and template-backed but never reaches NarrationService at runtime. Route room-entry/exit narration on player movement through generateNarration('movement', …).

Scope / Tasks

• Locate the movement/room-transition handler in ZoneRoom/movement command.
• Call generateNarration('movement', playerId, destinationRoomId, fallbackText) on successful move, non-blocking.
• Decide what recent_events context (e.g. direction moved) to pass; coordinate with Populate real narration context (fill ZoneRoom TODOs) #513 context fields.
• Add a wiring test asserting movement reaches narrate().

Acceptance Criteria

• Moving between rooms emits movement narration through the pipeline with template fallback.
• Test confirms the type is passed to narrate().

Dependencies

#513; Milestone A for live output.
