chore: sprint cleanup — language unification, parser unification, fossils removal

Several weeks of work accumulated without being committed. Grouped here for
clarity; see CHANGELOG.md [Unreleased] for the user-facing summary.

Highlights
----------

P1 #2 — ISO 639-2/B canonical migration
- New Language VO + LanguageRegistry (alfred/domain/shared/knowledge/).
- iso_languages.yaml as single source of truth for language codes.
- SubtitleKnowledgeBase now delegates lookup to LanguageRegistry; subtitles.yaml
  only declares subtitle-specific tokens (vostfr, vf, vff, …).
- SubtitlePreferences default → ["fre", "eng"]; subtitle filenames written as
  {iso639_2b}.srt (legacy fr.srt still read via alias).
- Scanner: dropped _LANG_KEYWORDS / _SDH_TOKENS / _FORCED_TOKENS /
  SUBTITLE_EXTENSIONS hardcoded dicts.
- Fixed: 'hi' token no longer marks SDH (conflicted with Hindi alias).
- Added settings.min_movie_size_bytes (was a module constant).

P1 #3 — Release parser unification + data-driven tokenizer
- parse_release() is now the single source of truth for release-name parsing.
- alfred/knowledge/release/separators.yaml declares the token separators used
  by the tokenizer (., space, [, ], (, ), _). New conventions can be added
  without code changes.
- Tokenizer now splits on any configured separator instead of name.split('.').
  Releases like 'The Father (2020) [1080p] [WEBRip] [5.1] [YTS.MX]' parse via
  the direct path without sanitization fallback.
- Site-tag extraction always runs first; well-formedness only rejects truly
  forbidden chars.
- _parse_season_episode() extended with NxNN / NxNNxNN alt forms.
- Removed dead helpers: _sanitize, _normalize.

Domain cleanup
- Deleted fossil services with zero production callers:
    alfred/domain/movies/services.py
    alfred/domain/tv_shows/services.py
    alfred/domain/subtitles/services.py (replaced by subtitles/services/ package)
    alfred/domain/subtitles/repositories.py
- Split monolithic subtitle services into a package (identifier, matcher,
  placer, pattern_detector, utils) + dedicated knowledge/ package.
- MediaInfo split into dedicated package (alfred/domain/shared/media/:
  audio, video, subtitle, info, matching).

Persistence cleanup
- Removed dead JSON repositories (movie/subtitle/tvshow_repository.py).

Tests
- Major expansion of the test suite organized to mirror the source tree.
- Removed obsolete *_edge_cases test files superseded by structured tests.
- Suite: 990 passed, 8 skipped.

Misc
- .gitignore: exclude env_backup/ and *.bak.
- Adjustments across agent/llm, app.py, application/filesystem, and
  infrastructure/filesystem to align with the new domain layout.

+"""Tests for ``alfred.agent.llm.deepseek.DeepSeekClient``.

+Thin wrapper around DeepSeek's OpenAI-compatible ``/v1/chat/completions``

+  raise ``LLMConfigurationError``.
+- ``TestCompleteValidation`` — empty list, non-dict element, missing role,
+  unknown role, missing content all raise ``ValueError``.
+- ``TestCompleteHappyPath`` — POSTs to correct URL with bearer header,
+  returns ``choices[0].message`` verbatim, threads ``tools`` into payload.
+- ``TestCompleteErrors`` — Timeout, HTTPError (with/without JSON body),
+  RequestException, malformed response (missing ``choices`` / ``message``,
+  ``TypeError`` from parsing) are all wrapped as ``LLMAPIError``.

+   bare Python function: name resolution, docstring → description, required
+   versus optional parameters, ``Optional[X]`` / ``X | None`` stripping, and
+   the Python-to-JSON-Schema type mapping (``str/int/float/bool/list/dict``
+   → ``string/integer/number/boolean/array/object``).
+
+2. **TestMakeTools** — Integration check on the live registry: every tool
+   declared in ``make_tools(settings)`` is a real ``Tool`` instance with a
+   callable ``func`` and a name matching its dict key, and a known core set
+   of tools is always present. Resolver tests target the four media-typed
+   resolvers (``resolve_movie_destination``, ``_season_``, ``_episode_``,
+   ``_series_``), not the legacy unified ``resolve_destination`` which no
+   longer exists.

-Tests for alfred.application.filesystem.resolve_destination
+"""Tests for ``alfred.application.filesystem.resolve_destination``.
 
-Uses a real temp filesystem + a real Memory instance (via conftest fixtures).
-No network calls — TMDB data is passed in directly.
+Four use cases compute library paths from a release name + TMDB metadata:
+
+- ``resolve_season_destination`` — folder move (series + season).
+- ``resolve_episode_destination`` — file move (full library_file path).
+- ``resolve_movie_destination`` — file move (folder + library_file).
+- ``resolve_series_destination`` — folder move (whole multi-season pack).
+
+Coverage:
+
+- ``TestSanitize`` — Windows-forbidden chars stripped.
+- ``TestFindExistingTvshowFolders`` — empty root, prefix match (case + space → dot).
+- ``TestResolveSeriesFolderInternal`` — confirmed_folder, no existing, single match,
+  ambiguous → _Clarification.
+- ``TestSeason`` — library_not_set, ok path, clarification path.
+- ``TestEpisode`` — library_not_set, ok path, filename includes episode_title, ext from source.
+- ``TestMovie`` — library_not_set, ok path, is_new_folder, sanitization.
+- ``TestSeries`` — library_not_set, ok path.
+- ``TestDTOToDict`` — each DTO's three states (ok / clarification / error).

+Coverage:

+- ``TestSuccess`` — full MediaResult with imdb_id → ok+imdb_id; missing

+- ``TestErrorTranslation`` — ``TMDBNotFoundError`` → not_found,

+- ``TestPassThrough`` — query is forwarded to the client unchanged.

+- ``TestCountEntries`` — last-cue-number heuristic for SRT files.
+- ``TestEmbedded`` — ffprobe is mocked; dispositions map to SDH/FORCED
+  / STANDARD; non-existent file → empty list; ffprobe error → empty.
+- ``TestAdjacent`` — adjacent strategy: only known extensions, excludes
+  the video file itself.
+- ``TestFlat`` — Subs/ folder adjacent or at release root.
+- ``TestEpisodeSubfolder`` — Subs/{stem}/*.srt; tokens after prefix.
+- ``TestClassify`` — language + type token detection, confidence math.
+- ``TestSizeDisambiguation`` — size_and_count post-processing rules
+  (2-track → standard+sdh; 3+ → forced + standard + sdh).

+- ``TestAdjacentDetection`` — .srt next to the video → ``adjacent``.
+- ``TestFlatSubsFolder`` — ``Subs/*.srt`` → ``subs_flat``.

+- ``TestNothingFound`` — empty release returns no pattern.
+- ``TestDescribe`` — human-readable description mentions the right cues.

+"""Tests for ``alfred.infrastructure.api.qbittorrent.client.QBittorrentClient``.
+
+Exercises every public method against a ``MagicMock`` ``requests.Session``
+attached to the client. Auth state (``self._authenticated``) is asserted
+explicitly so the implicit auto-login behavior of mutation methods is
+covered.
+
+Scope:
+
+- ``TestInit`` — host/credentials wiring + Session attached.
+- ``TestMakeRequest`` — verb dispatch (GET/POST), JSON vs text fallback,
+  error translation for timeout/403/5xx/RequestException, invalid verb.
+- ``TestLogin`` — happy path, non-"Ok." rejection, propagation from
+  underlying API error.
+- ``TestGetTorrents`` — auto-login, non-list payload safety, per-item parse
+  failures.
+- ``TestAddTorrent`` — magnet payload wiring, optional category/save_path,
+  paused flag, unexpected response.
+- ``TestMutations`` — pause/resume/delete/recheck/set_location all wire the
+  hash and propagate errors.
+- ``TestFindByName`` — exact match, case-insensitive match, save_path fallback,
+  no match.
+- ``TestParseTorrent`` — progress percentage conversion, defaults.

+- ``filesystem_operations.create_folder`` / ``move`` — thin

+"""Tests for ``alfred.infrastructure.metadata.store.MetadataStore``.
+
+The store manages ``<release_root>/.alfred/metadata.yaml`` — a per-release
+sidecar with parse, probe, TMDB, pattern, and subtitle-history sections.
+
+Coverage:
+
+- ``TestIdentityAndExists`` — accessors + ``exists()``.
+- ``TestLoad`` — empty/missing/corrupt YAML returns ``{}``.
+- ``TestSave`` — atomic write creates ``.alfred/`` + temp file is gone.
+- ``TestUpdateSection`` — replaces the section + adds ``_updated_at``.
+- ``TestUpdateParse/Probe/Tmdb`` — strips ``status`` from payload;
+  TMDB promotes ``imdb_id`` / ``tmdb_id`` / ``media_type`` / ``title``
+  to the top level.
+- ``TestPattern`` — ``confirmed_pattern`` returns the id only when flag
+  is set; ``mark_pattern_confirmed`` preserves pre-existing keys.
+- ``TestSubtitleHistory`` — append + release-group dedup.

+- **Step loop** — ``step(user_input)`` records the user message, builds the

+  returns the final assistant text.
+
+These tests use the current component-based LTM API
+(``memory.ltm.workspace.download``, ``memory.ltm.library_paths.set(...)``).

+- ``ShortTermMemory`` — session-only conversation/workflow/entity state.

+- ``Memory`` — unified manager (load/save LTM, clear session).

+   if a step id, tool name, or naming convention is renamed, the test
+   surfaces the change immediately. They use the real loader with no
+   monkeypatching.
+
+2. **TestLoaderMechanics** — Loader behavior in isolation, using a
+   monkeypatched workflows directory. Covers ``get`` / ``names`` / ``all``,
+   YAML ``name`` precedence over filename, malformed-file resilience,
+   deterministic ordering on name collision, and the empty-directory case.
+
+Current workflow naming convention is ``<domain>.<workflow_name>``
+(e.g. ``media.organize_media``), not the legacy bare ``organize_media``.
