Shared cache/rescan-duration logic in common.sh now takes an arr_type
param instead of being Lidarr-specific, so Sonarr and Radarr cleanup
scripts get the same cache-first fetch + rescan-aware retry Lidarr had.
Avoids redundant full-library API calls across scripts run back to back,
and stops false failures when a fetch lands mid-rescan.
Shared cache (lidarr_get_tracked_data() in common.sh) so scripts stop
hitting Lidarr's live API for tracked counts every run, and stop
treating a mid-rescan dip as a genuine problem — a whole-library
RescanFolders legitimately makes trackFileCount read far below normal
while it re-verifies every file (confirmed 2026-07-16: 22% of normal
mid-scan). Cache reads fresh-if-recent, waits out an active rescan
(calibrated to that command's own historical duration, tracked per
command name since RescanFolders and DownloadedAlbumsScan take wildly
different amounts of time), then falls back to a stale cache rather
than hard-failing after a few strikes.
lidarr_cleanup.sh: no longer stacks a fresh DownloadedAlbumsScan on
top of one already running, and the tracked-count floor check now
waits out a genuine rescan instead of aborting on every overlap.
lidarr_duplicate_artist_cleanup.sh (new): finds case-insensitive
duplicate artist entries — same display name, different MusicBrainz
ID, added when a search/list-sync matches the wrong same-named artist.
Deletes the empty phantom side and blocks it from Import List
Exclusions, leaves genuinely-different-real-artists alone (checked by
album title overlap, deduped per-artist first so a legitimate reissue
under an artist's own catalog doesn't false-flag as cross-artist
overlap), and only notifies for the rare case where both sides have
real, overlapping content.
lidarr_cache_prefill.sh (new): warms the cache at array start so nothing
reads it cold after boot.
lidarr_missing_art.sh, lidarr_release_fixer.sh: write-through the cache
as a side effect of fetches they already needed for their own purposes.
