fix(mcp): align ChronoMind type enums with actual backend schema

Fix 3 type mismatches in MCP chronomind-client.ts + chronomind-tools.ts:

1. TimerDoc.type: Remove non-existent 'event', keep 'countdown'|'alarm'|'pomodoro'
2. TimerDoc.state: Remove non-existent 'idle', add missing 'snoozed'|'dismissed'
3. RoutineDoc.status: Replace wrong 'idle'|'running' with actual
   'template'|'ready'|'active'|'cancelled'

Fix cascading usages:
- chronomind.timers.create tool: default state 'idle' → 'active'
- chronomind.timers.list tool: update type/state enum in Zod schema + description
- calendar-import-pipeline.ts: 'idle' → 'active' for imported timers

MCP server typecheck passes. No runtime behavior change for existing tools.
