test(fixtures): seed SHITTY release bucket with 15 anti-regression cases

Add 15 expected.yaml fixtures under tests/fixtures/releases/shitty/
covering the awkward but real-world release names from the downloads
folder. Each fixture locks in the current parse_release behavior so
future parser changes are intentional, not silent drift.

Cases captured:
- Angel INTEGRALE 3-level hierarchy (tv_complete media_type)
- Buffy custom French title with dots preserved
- Archer S14E09E10E11 multi-episode (E11 lost — tech debt)
- Notre Planète lowercase s01e01
- Vinyl ' - 1x01 - FHD' (stray dash artifact — tech debt)
- Deutschland.83 (year-suffix as part of title)
- Tatortreiniger S01-06 range (falls to movie — tech debt)
- Derry Girls duplicated title
- Jurassic Park bare folder (media_type=unknown)
- La Nuit au Musée bilingual MULTI
- Chérie j'ai agrandi (ASCII-stripped apostrophe, parses fine)
- Honey Don't (unescaped apostrophe — full AI-path degeneration)
- Hook MULTi.SUBS movie with Subs/ folder
- Predator Badlands space separators (group=UNKNOWN — tech debt)
- Westworld S04 Subs.Only (no video file)

Each fixture also captures the future 3-flow routing (library /
torrents / seed_hardlinks) ahead of the organize_media refactor.

Suite: 1011 passed, 8 skipped.
