### Added
- Lightweight channel summary API endpoint: Added a new `/api/channels/summary/` endpoint that returns only the minimal channel data needed for TV Guide and DVR scheduling (id, name, logo), avoiding the overhead of serializing full channel objects for high-frequency UI operations.
- Event-driven webhooks and script execution (Connect): Added new Connect feature that enables event-driven execution of custom scripts and webhooks in response to system events. Supports multiple event types including channel lifecycle (start, stop, reconnect, error, failover), stream operations (switch), recording events (start, end), data refreshes (EPG, M3U), and client activity (connect, disconnect). Event data is available as environment variables in scripts (prefixed with `DISPATCHARR_`), POST payloads for webhooks, and plugin execution payloads. Plugins can now subscribe to events by specifying an `events` array in their action definitions. Includes connection testing endpoint with dummy payloads for validation. (Closes #203)
- Cron scheduling support for M3U and EPG refreshes: Added interactive cron expression builder with preset buttons and custom field editors, plus info popover with common cron examples. Refactored backup scheduling to use shared ScheduleInput component for consistency across all scheduling interfaces. (Closes #165)
- Channel numbering modes for auto channel sync: Added three channel numbering modes when auto-syncing channels from M3U groups:

### Changed
- Channel store optimization: Refactored frontend channel loading to only fetch channel IDs on initial login (matching the streams store pattern), instead of loading full channel objects upfront. Full channel data is fetched lazily as needed. This dramatically reduces login time and initial page load when large channel libraries are present.
- TV Guide performance improvements: Optimized the TV Guide with horizontal culling for off-screen program rows (only rendering visible programs), throttled now-line position updates, and improved scroll performance. Reduces unnecessary DOM work and improves responsiveness with large EPG datasets.
- XC API M3U stream URLs: M3U generation for Xtream Codes API endpoints now use proper XC-style stream URLs (`/live/username/password/channel_id`) instead of UUID-based stream endpoints, ensuring full compatibility with XC clients. (Fixes #839)
### Fixed
- DVR one-time recording scheduling: Fixed a bug where scheduling a one-time recording for a future program caused the recording to start immediately instead of at the scheduled time.
- Auto channel sync duplicate channel numbers across groups: Fixed issue where multiple auto-sync groups starting at the same number would create duplicate channel numbers. The used channel number tracking now persists across all groups in a single sync operation, ensuring each assigned channel number is globally unique.
- Modular mode PostgreSQL/Redis connection checks: Replaced raw Python socket checks with native tools (`pg_isready` for PostgreSQL and `socket.create_connection` for Redis) in modular deployment mode to prevent indefinite hangs in Docker environments with non-standard networking or DNS configurations. Now properly supports IPv4 and IPv6 configurations. (Fixes #952) - Thanks [@CodeBormen](https://github.com/CodeBormen)
