Add mission briefing system that displays when entering VR and requires
trigger pull to dismiss before gameplay begins. This prevents accidental
weapon firing and provides clear mission objectives to players.
## Key Features
- Mission brief displays on VR entry with objectives from directory.json
- Ship controls disabled during briefing (movement, rotation, weapons)
- Either controller trigger dismisses brief and starts game timer
- First trigger pull does not fire weapons, only dismisses briefing
- Subsequent trigger pulls fire weapons normally
## Implementation Details
- Added MissionBrief class with mesh-based UI parented to ship
- Ship class gains disableControls()/enableControls() methods
- New mission brief trigger observable bypasses normal shoot handling
- ControllerInput modified to allow triggers through when disabled
- Level1 orchestrates control flow: disable → show brief → enable
- Game timer and physics recording start only after dismissal
## Technical Changes
- controllerInput.ts: Allow trigger events when controls disabled
- ship.ts: Add control state tracking and mission brief observable
- level1.ts: Integrate mission brief into XR initialization flow
- missionBrief.ts: New class for displaying briefing with trigger detection
- Fixed property name mismatch in level selection event dispatch
- Added cache-busting for dev mode level loading
- Exposed LevelRegistry to window for debugging

Implements a flexible, provider-agnostic analytics system with New Relic adapter featuring intelligent event batching for cost optimization.
Features:
- Type-safe event tracking with TypeScript interfaces
- Pluggable adapter architecture for multiple providers
- Intelligent batching (reduces data usage by 70-90%)
- Event sampling for high-volume events
- Zero breaking changes to existing New Relic setup
- Debug mode for development testing
Integration points:
- Session tracking in main.ts
- Level start and WebXR events in level1.ts
- Asteroid destruction and hull damage in ship.ts
- Performance snapshots and session end in gameStats.ts
Events tracked:
- session_start, session_end
- webxr_session_start
- level_start
- asteroid_destroyed (20% sampled)
- hull_damage
- gameplay_snapshot (60s intervals, 50% sampled)
Cost optimization:
- Batching reduces individual events by ~70%
- Sampling reduces high-frequency events by 50-80%
- Combined savings: ~90% data reduction
- Keeps usage safely under New Relic free tier (100GB/month)
