feat(scheduled-ops): add failure notifications, granular targeting, and history export (#286)

- Dispatch error alerts via NotificationService when scheduled tasks fail,
  with info-level recovery notifications when a previously-failing task succeeds
- Per-service restart targeting: scheduled stack restarts can target specific
  services instead of restarting the entire stack
- Prune label filter: scheduled prune operations can be scoped to resources
  matching a specific Docker label
- CSV export button in the execution history panel for one-click download
- Fix: prune_targets was silently dropped on task creation (missing in INSERT)

 ## [Unreleased]
 
+### Added
+
+* **scheduled-ops:** failure notifications — dispatches error alerts through configured notification channels (Discord, Slack, webhook) when a scheduled task fails, with info-level recovery notifications when a previously-failing task succeeds again
+* **scheduled-ops:** per-service restart targeting — scheduled stack restarts can now target specific services rather than restarting the entire stack
+* **scheduled-ops:** prune label filter — scheduled system prune operations can be scoped to resources matching a specific Docker label (e.g. `com.docker.compose.project=mystack`)
+* **scheduled-ops:** CSV export for execution history — one-click download of the full run history from the execution history panel
+
+### Fixed
+
+* **scheduled-ops:** `prune_targets` field was silently dropped when creating scheduled tasks due to missing column in the INSERT statement
+
 ### Security
 
 * **docker:** upgrade Docker Compose from v2.40.3 to v5.1.1 to remediate 5 Go stdlib/x/crypto CVEs (CVE-2025-68121, CVE-2025-61726, CVE-2025-61729, CVE-2026-25679, CVE-2025-47913). Compose v2.40.3 was compiled with Go 1.24.9 and x/crypto 0.38.0; v5.1.1 ships Go 1.25.8 and x/crypto 0.46.0. Docker CLI remains at v29.3.1 (already patched). CVE-2026-33186 (grpc ≥1.79.3) cannot be resolved until upstream Docker/Compose releases upgrade past grpc 1.78.0.

+## Granular Targeting
+
+### Per-Service Restart
+
+When creating a Restart Stack schedule, you can target individual services instead of restarting the entire stack. After selecting a stack, Sencho reads the compose file and displays checkboxes for each defined service. Select the services you want to restart, or leave all unchecked to restart every service in the stack.

+
+### Prune Label Filter
+
+When creating a System Prune schedule, you can scope the prune to resources matching a specific Docker label. This lets you target resources from a particular stack or project without affecting unrelated containers, images, or volumes.
+
+Enter a label in `key=value` format (e.g. `com.docker.compose.project=mystack`). Leave the field empty to prune all unused resources of the selected types.

 - **Delete** - Click the trash icon to permanently remove the task and all its execution history.
 
+## Failure Notifications
+
+When a scheduled task fails, Sencho automatically dispatches an **error-level alert** through your configured notification channels (Discord, Slack, or custom webhooks). The alert includes the task name, action type, and error message so you can diagnose the issue immediately.
+
+When a previously failing task succeeds again, Sencho sends an **info-level recovery notification** to confirm the issue is resolved. This recovery-only approach avoids notification noise from tasks that succeed on every run.
+
+To configure notification channels, go to **Settings > Notifications**.
