fix(release/parser): recognize Sxx-yy season range as tv_complete

`Der.Tatortreiniger.S01-06.GERMAN...` previously parsed as a movie
with 'S01-06' glued to the title. The parser now matches the
season-range form in _parse_season_episode (returning season=first,
episode=None), and the assemble step detects the range token to
promote media_type to 'tv_complete'.

The first season is exposed as `season` so `is_season_pack`
fires (season is not None and episode is None) — useful for routing
to a series root folder.

Fixture shitty/tatortreiniger_flat_multiseason/ updated:
- title: Der.Tatortreiniger.S01-06 → Der.Tatortreiniger
- season: null → 1
- media_type: movie → tv_complete
- is_season_pack: false → true
