Merge branch 'dev/sprint-cleanup'

Multi-week sprint: ISO 639-2/B language unification, release parser
unification + data-driven tokenizer, removal of fossil services
(movies/tv_shows/subtitles), subtitle services split into a package,
MediaInfo split, test suite expansion (990 passing).

See CHANGELOG.md [Unreleased] for the user-facing summary.

+Two suites:

+   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).

+- ``TestLoader`` — builtin loads alone, learned overlays add tokens,

+- ``TestKnowledgeBase`` — typed view: formats / languages /

+"""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.

+"""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.

+- **Construction** — ``Agent(settings, llm, max_tool_iterations)`` wires the

+- **Tool execution** — ``_execute_tool_call`` parses an OpenAI-shaped

+- **Step loop** — ``step(user_input)`` records the user message, builds the
+  system prompt, runs the LLM/tool loop up to ``max_tool_iterations``, and
+  returns the final assistant text.
+
+These tests use the current component-based LTM API
+(``memory.ltm.workspace.download``, ``memory.ltm.library_paths.set(...)``).
+The legacy flat attributes (``download_folder``, ``movie_folder``, …) no
