Deluan Quintão 668869b6c7 feat(plugins): add TaskQueue host service for persistent background task queues (#5116)
* feat(plugins): define TaskQueue host service interface

Add the TaskQueueService interface with CreateQueue, Enqueue,
GetTaskStatus, and CancelTask methods plus QueueConfig struct.

* feat(plugins): define TaskWorker capability for task execution callbacks

* feat(plugins): add taskqueue permission to manifest schema

Add TaskQueuePermission with maxConcurrency option.

* feat(plugins): implement TaskQueue service with SQLite persistence and workers

Per-plugin SQLite database with queues and tasks tables. Worker goroutines
dequeue tasks and invoke nd_task_execute callback. Exponential backoff
retries, rate limiting via delayMs, automatic cleanup of terminal tasks.

* feat(plugins): require TaskWorker capability for taskqueue permission

* feat(plugins): register TaskQueue host service in manager

* feat(plugins): add test-taskqueue plugin for integration testing

* feat(plugins): add integration tests for TaskQueue host service

* docs: document TaskQueue module for persistent task queues

Signed-off-by: Deluan <deluan@navidrome.org>

* fix(plugins): harden TaskQueue host service with validation and safety improvements

Add input validation (queue name length, payload size limits), extract
status string constants to eliminate raw SQL literals, make CreateQueue
idempotent via upsert for crash recovery, fix RetentionMs default check
for negative values, cap exponential backoff at 1 hour to prevent
overflow, and replace manual mutex-based delay enforcement with
rate.Limiter from golang.org/x/time/rate for correct concurrent worker
serialization.

* refactor(plugins): remove capability check for TaskWorker in TaskQueue host service

Signed-off-by: Deluan <deluan@navidrome.org>

* fix(plugins): use context-aware database execution in TaskQueue host service

Signed-off-by: Deluan <deluan@navidrome.org>

* refactor(plugins): streamline task queue configuration and error handling

Signed-off-by: Deluan <deluan@navidrome.org>

* feat(plugins): increase maxConcurrency for task queue and handle budget exhaustion

Signed-off-by: Deluan <deluan@navidrome.org>

* refactor(plugins): simplify goroutine management in task queue service

Signed-off-by: Deluan <deluan@navidrome.org>

* feat(plugins): update TaskWorker interface to return status messages and refactor task queue service

Signed-off-by: Deluan <deluan@navidrome.org>

* feat(plugins): add ClearQueue function to remove pending tasks from a specified queue

Signed-off-by: Deluan <deluan@navidrome.org>

* refactor(plugins): use migrateDB for task queue schema and fix constant name collision

Replaced the raw db.Exec call in createTaskQueueSchema with migrateDB,
matching the pattern used by createKVStoreSchema. This enables version-tracked
schema migrations via SQLite's PRAGMA user_version, allowing future schema
changes to be appended incrementally. Also renamed cleanupInterval to
taskCleanupInterval to resolve a redeclaration conflict with host_kvstore.go.

* regenerate PDKs
