v3.8.8 — LazyLibrarian Compat, qBittorrent 2.11.2 API, Torznab Query Hardening

✨ Added

• LazyLibrarian → aMuTorrent → aMule support. Multipart POST /api/v2/torrents/add handling (LazyLibrarian sends the dummy-file variant even for magnet URLs), new GET /api/v2/torrents/properties and GET /api/v2/torrents/files endpoints for LazyLibrarian's post-add verification and post-download file discovery, and invalidateBatchCache() on successful add so the next torrents/info poll sees fresh data (Sonarr/Radarr get the same small QoL win). savepath sent alongside urls is mapped to a matching aMule category by path when no category/label is set, with explicit warnings when the path doesn't match anything (#71, contributed by @Mika3578).
• qBittorrent WebAPI ≥2.11.2 route aliases. POST /torrents/stop and POST /torrents/start alias pauseTorrent / resumeTorrent respectively — real qBit renamed those in 2.11.2, and clients like Medusa key off the advertised webapiVersion (2.11.4) and call the new names. New POST /torrents/setCategory handler; returns 409 text/plain "Category does not exist" when the requested name isn't in the compat categories cache, matching qBit exactly so clients trigger the createCategory + retry handshake (#74).

🐛 Fixed

• rTorrent 0.16.18 stuck showing "Firewalled" regardless of actual state. rTorrent 0.16.18 deprecated network.port_open; our multicall was still calling it and falling into the false branch. That command was never a real firewall check anyway — it was a config toggle. Replaced with network.listen.port > 0 (rTorrent is actually bound and listening), forward-compatible with 0.16.18 and backward-compatible with older builds.
• size / downloaded / completed shipped as JSON strings, crashing Medusa (unsupported operand type(s) for /: 'str' and 'str'). Real qBit returns numbers; Sonarr/Radarr's .NET deserializer coerces silently, but strict consumers (Python, typed Go/Rust) don't. Root cause: _mapUnifiedItemToDownload was needlessly String()-casting numeric fields on the way in, and the converter passed them through verbatim. Fixed at both layers: source (drop the casts) and output boundary (Number()-coerce every numeric field before returning). Covers size, total_size, amount_left, downloaded, completed, downloaded_session, uploaded, uploaded_session, dlspeed, upspeed, ratio (#72).
• Torznab returned 0 items for long q values (Medusa passes series name + full episode title as free-text). aMule's SearchList.cpp:104 rejects a parsed expression when boolean operators exceed 10; the grammar inserts an implicit AND per adjacent-word pair, so 12+ words trips "Search expression is too complex". Long queries are now capped at 11 words (10 for tvsearch, reserving 1 for the appended format token), with a warn-level log so users can correlate. tvsearch also emits an absolute-style variant (Show 05) alongside the existing 1x05 / S01E05 — catches ED2K releases named "Show 01 - Title" (common French / documentary / anime naming). If all season/episode variants collectively return 0, falls back to a single retry with the bare (capped) series name (#73).

♻️ Improved

• qBittorrent-compat polish. _findTorrentInfoByHash enriches only the matched candidate instead of every one (O(N) → O(1) enrich calls per lookup); negative-result cache (5s TTL, cleared on successful add) so bogus-hash polls don't refetch aMule on every request; 404 responses on properties / files now text/plain matching qBit; npm test script portable across all shells (test/**/*.test.js glob replaced with test/ directory recursion).
