- Strip standalone reissue keywords (remaster/remastered/remix/deluxe/
expanded/edition/reissue/anniversary/bonus) regardless of brackets so
non-parenthesized remasters still match the plain local title above the
0.85 threshold (was falsely reported missing).
- Fix TestAppRun_ScanLogsMissingReleases to verify run() performs the
scan itself (capture its log output) instead of re-running ScanAll
independently, which passed even if run() were a no-op.
- Fix TestSimilarity misleading cases that downgraded to a <0.85 range
check with dead want/epsilon fields; assert actual computed scores.
Add FindMissingReleases and MissingRelease to internal/scanner: skips
IsIgnored external releases, scopes matches per ArtistID, and reports
external releases with no local album above the fuzzy threshold.
