Adds soft-delete support for local users, including backend, API, and UI changes to allow admins to delete local users while preserving their requests. Updates user queries to exclude deleted users and allows username reuse for deleted accounts. Refines search and ranking logic for torrents: uses title-only queries for broader results, increases max results to 100, applies a minimum score threshold (30/100), and logs detailed ranking breakdowns. Updates the ranking algorithm to prioritize title/author match, adjusts scoring weights, and improves BookDate compatibility with Audiobookshelf by disabling rating-based features when unsupported. Enhances file copy operations for large files, improves metadata tagging, and updates documentation to reflect new search and ranking strategies.
**Problem:** Prowlarr searches were querying ALL indexers instead of only
the ones enabled in user settings, causing torrents to be selected from
disabled/untrusted indexers.
**Root Cause:** The prowlarr.search() method didn't filter by indexer IDs,
and callers weren't passing enabled indexer IDs to the search.
**Changes:**
1. Added indexerIds parameter to SearchFilters interface
2. Updated prowlarr.service.ts search() to filter by indexerIds
3. Updated search-indexers.processor.ts to fetch and pass enabled indexer IDs
4. Updated interactive-search route to fetch and pass enabled indexer IDs
5. Added validation: search fails if no indexers are configured/enabled
6. Updated documentation to reflect indexer filtering behavior
**Impact:**
- Manual search: Only searches enabled indexers
- Interactive search: Only searches enabled indexers
- RSS monitoring: Already correctly filtered (no changes needed)
**Testing:** TypeScript type checking passed with no errors
