* feat: add persistent environments with hybrid DB + Redis storage [LET-7721]
Implements persistent storage for letta-code listener connections (environments) with hybrid PostgreSQL + Redis architecture:
**Database Layer:**
- Add `environments` table with device tracking, connection metadata, soft deletes
- Store userId/apiKeyOwner, connection history (firstSeenAt, lastSeenAt)
- Unique constraint on (organizationId, deviceId) - one environment per device per org
- Auto-undelete previously deleted environments on reconnect
**API Layer:**
- Update environmentsContract with new fields (id, firstSeenAt, lastSeenAt, metadata)
- Add deleteEnvironment endpoint (soft delete, closes WebSocket if online)
- Add onlineOnly filter to listConnections for efficient online-only queries
- Export ListConnectionsResponse type for proper client typing
**Router Implementation:**
- register(): Create/update DB environment, generate ephemeral connectionId
- listConnections(): Hybrid query strategy (DB-first for all, Redis-first for onlineOnly)
- deleteEnvironment(): Soft delete with Redis Pub/Sub for graceful WebSocket close
- Filter by connectionId in DB using inArray() for onlineOnly performance
**WebSocket Handler:**
- Moved from apps/cloud-api to libs/utils-server for reusability
- Update DB on connect/disconnect only (not heartbeat) - minimal write load
- Store currentPodId and userId/apiKeyOwner on connect
- Clear currentConnectionId/currentPodId on disconnect/error
**Shared Types:**
- Add EnvironmentMetadata interface in libs/types for cross-layer consistency
- Update Redis schema to include currentMode field
**UI Components:**
- Add DeleteDeviceModal with offline-only restriction
- Update DeviceSelector with delete button on hover for offline devices
- Proper cache updates using ListConnectionsResponse type
- Add translations for delete modal

* docs: update letta remote setup instructions [LET-7721]
Update local setup guide with clearer instructions:
- Remove hardcoded ngrok URL requirement (ngrok generates URL automatically)
- Update env var to use CLOUD_API_ENDPOINT_OVERRIDE
- Add proper API key and base URL format
- Include alternative setup using letta-code repo with bun dev

* chore: fix env
* fix: lint errors and make migration idempotent [LET-7721]
- Remove unused imports (HiddenOnMobile, VisibleOnMobile, MiddleTruncate)
- Fix type imports (use `import type` for type-only imports)
- Remove non-null assertions in environmentsRouter (use safe null checks + filter)
- Make migration idempotent with IF NOT EXISTS for table, indexes, and constraints
- Use DO $$ block for foreign key constraint (handles duplicate_object exception)
