merge branch 'develop' into 'main' - Release v1.7.35

- Update README Proxy Routes section to explicitly state only a selective subset of endpoints is exposed
- Replace wildcard API endpoint listings with complete list of 30 specific implemented proxy endpoints
- Update OpenAPI tag descriptions for Sonarr/Radarr to clarify selective proxy scope

+## [1.7.35] - 2026-05-29
+
+### Added
+
+- **Orphaned *arr Queue Item Support (Issue #73)** — Added support for active Sonarr/Radarr queue items from unconfigured download clients ("orphaned" downloads). Added a new synthetic client (`'orphaned'`) with a custom viewBox vector graphics asset at `/images/clients/orphaned.svg` to represent unconfigured clients, and updated filter dropdown lists and active downloads grids to cleanly display them with a dimmed logo, custom dashed border styling, and informative hover tooltips. Resolves Gitea Issue [#73](https://git.i3omb.com/Gandalf/sofarr/issues/73).
+
+### Enhanced
+
+- **Download Matching & JSDoc Hygiene (Issue #73)** — Refactored core active-download matching algorithms into unified, deduplicated helper functions (`normalizeTitle`, `titleMatches`, `buildArrDownload`) in `DownloadMatcher.js`, preventing hundreds of lines of duplicate code. Handled case-insensitive and type-safe `downloadId` lookup in `matchSabHistory` across both history and active queue records. Added safe progress arithmetic bounds checking to prevent division-by-zero or `NaN`.
+
+### Fixed
+
+- **Security Metadata Isolation in buildArrDownload (Issue #73)** — Restricted access control for sensitive properties like `arrInstanceKey` (the raw instance API key) to ensure they are strictly stripped out of download objects for non-administrator users, preserving system security boundaries.

These endpoints reflect the APIs of Sonarr, Radarr, SABnzbd, and Emby respectively, and are documented to show the specific endpoints implemented in sofarr (not the full upstream API surface).
