dedup: modulo audio fingerprinting via fpcalc + cache SQLite

Nuovo modulo core.dedup per rilevare brani audio duplicati usando
Chromaprint (fpcalc): scan cartella (opzionalmente ricorsivo),
fingerprint acustico via fpcalc -json, cache SQLite in
_get_config_dir()/dedup_cache.db per non ricalcolare al re-scan,
raggruppamento per fingerprint identico + ordering per bitrate DESC.
move_to_trash() usa send2trash (reversibile via Finder/Explorer).

- core/paths.py: find_fpcalc() con fallback dev su project bundle_bin
- core/dedup.py: scan_folder, compute_fingerprint, move_to_trash
- tests/test_dedup.py: 9 unit test (mock fpcalc + send2trash)
- requirements.txt: send2trash>=1.8.0
- build_macos.py: download fpcalc universal binary da GitHub releases
- build_windows.py: download fpcalc.exe da GitHub releases
