Add database foundation for observability features:
- event_log table with severity/source filtering and pagination
- standalone_proxies table for user-created reverse proxies
- stale_threshold_days setting (default 7 days)
- Auto-persist warn/error events from event bus to database
- SSE broadcast of persistent events for real-time UI updates
- Frontend types and API functions for downstream UI phases
Add enable_proxy boolean to stages (default true). When disabled,
the deployer skips NPM proxy host creation — useful for internal
services, workers, or externally-routed containers. UI shows
toggle in Add Stage form and "No Proxy" badge on stage header.
Add global base_volume_path to settings. Relative volume source
paths are automatically prepended with the base path at deploy
time. Absolute paths are used as-is. Configurable in Settings >
General.
Per-stage env var overrides with encryption for secrets.
Volume mounts with shared/isolated modes (isolated appends
/{stage}-{tag}/ to source path). Store CRUD, API endpoints,
and frontend editors for both. Env merge during deploy.
Initialize Go module, directory structure, and full SQLite store layer:
- 7-table schema (projects, stages, registries, settings, instances,
deploys, deploy_logs) with auto-migration
- CRUD operations for all entities with proper error handling
- ErrNotFound sentinel for distinguishing 404 from 500 in handlers
- WAL mode, foreign keys, busy timeout pragmas
