fix: address code review findings

- 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.
