refactor(domain): freeze Movie and Episode, switch track collections to tuple

Movie and Episode become @dataclass(frozen=True, eq=False), with
audio_tracks/subtitle_tracks held as tuple[...] instead of list[...].
Identity-based equality is preserved via the existing __eq__/__hash__.
__post_init__ coercion (imdb_id, title, season_number, episode_number)
uses object.__setattr__ to stay compatible with frozen.

The MediaWithTracks mixin contract is updated to tuple accordingly.

Callers projecting enrichment results (probe output, file metadata) now
rebuild via dataclasses.replace(...) — same pattern recently adopted for
ParsedRelease.

Season and TVShow stay mutable for now: freezing the aggregate root
would cascade a full reconstruction on every add_episode, deferred.

 ### Added
 
+- **Fullwidth vertical bar `｜` (U+FF5C) is now a recognized release-name
+  token separator.** Added to `alfred/knowledge/release/separators.yaml`
+  so CJK release names (and the occasional decorative YouTube-style use)
+  tokenize cleanly instead of leaving the wide pipe glued onto an
+  adjacent token. The tokenizer in
+  `alfred/domain/release/parser/pipeline.py` already iterates the
+  separator list as plain strings (no regex), so a multi-byte UTF-8
+  separator works without any code change.
+
+- **`InspectedResult.recommended_action` property** — derived hint that
+  collapses the orchestrator's go / wait / skip decision into a single
+  value (``"process"`` / ``"ask_user"`` / ``"skip"``). Centralizes the
+  exclusion logic that was previously dispersed across road /
+  media_type / main_video checks at each call site. Ordering is part of
+  the contract: ``skip`` (no main video, or media_type == ``"other"``)
+  wins over ``ask_user`` (media_type == ``"unknown"`` or road ==
+  ``"path_of_pain"``) which wins over ``process``. Surfaced through the
+  ``analyze_release`` tool so the LLM can route on it directly.
+  6 new tests in ``tests/application/test_inspect.py`` cover the four
+  branches and the precedence rules.
 - **`LanguageRepository` port** in `alfred.domain.shared.ports`. Structural
   Protocol covering `from_iso`, `from_any`, `all`, `__contains__`, `__len__`
   — the surface previously coupled to the concrete `LanguageRegistry`.

 ### Changed
 
+- **`Movie` and `Episode` are now frozen dataclasses.** Both entities
+  hold their track collections as `tuple[AudioTrack, ...]` and
+  `tuple[SubtitleTrack, ...]` instead of mutable lists, and are
+  `@dataclass(frozen=True, eq=False)` (identity-based equality
+  preserved via `__eq__`/`__hash__`). `__post_init__` coercion uses
+  `object.__setattr__` for the `imdb_id` / `title` /
+  `season_number` / `episode_number` normalizations. To project
+  enrichment results (probe output, file metadata) callers now rebuild
+  via `dataclasses.replace(...)`. Pattern aligned with the recent
+  `ParsedRelease` freeze. `MediaWithTracks` mixin contract updated to
+  `tuple` accordingly. `Season` and `TVShow` remain mutable for now —
+  freezing the aggregate root would cascade a full reconstruction on
+  every `add_episode`, deferred.
+- **`SubtitleCandidate` renamed to `SubtitleScanResult`.** The old name
+  conflated "this might become a placed subtitle" with "this is what a
+  scan pass produced". The class is the output of a scan/identify pass
+  — language/format may still be `None`, confidence reflects how sure
+  the classifier is, and `raw_tokens` holds the filename fragments
+  under analysis. `SubtitleScanResult` says that directly. Pure rename
+  with a refreshed docstring in `alfred/domain/subtitles/entities.py`;
+  no behavior change. Touches the domain entity + `__init__` export,
+  the matcher / identifier / utils services, the manage_subtitles use
+  case, the placer, the metadata store, the shared-media cross-ref
+  comment, and the seven test modules that imported the type.
+
+- **`ParsedRelease` is now frozen; enrichment passes return new
+  instances.** The VO was mutable so `detect_media_type` and
+  `enrich_from_probe` could patch fields in place — a code smell in a
+  value object whose identity *is* its content. `ParsedRelease` is now
+  `@dataclass(frozen=True)`; `languages` is a `tuple[str, ...]`
+  instead of a `list[str]`. `enrich_from_probe` returns a new
+  `ParsedRelease` via `dataclasses.replace` (only allocates when at
+  least one field actually changed). `inspect_release` rebinds
+  `parsed` after both `detect_media_type` (wrapped in `MediaTypeToken`
+  to satisfy the strict isinstance check that now also runs on
+  replace) and `enrich_from_probe`. Parser pipeline now packs
+  `languages` as a tuple in the assemble dict. Callers updated:
+  `inspect_release`, `testing/recognize_folders_in_downloads.py`, and
+  the enrichment tests (22 call sites + language assertions switched
+  to tuple literals).
+- **`resolve_destination` use cases take `kb` / `prober` as required
+  params; module-level singletons gone.** The four
+  `resolve_{season,episode,movie,series}_destination` use cases now
+  accept `kb: ReleaseKnowledge` and `prober: MediaProber` as required
+  arguments, matching the shape of `inspect_release`. The module-level
+  `_KB = YamlReleaseKnowledge()` and `_PROBER = FfprobeMediaProber()`
+  singletons that previously lived in
+  `alfred/application/filesystem/resolve_destination.py` are removed —
+  the application layer no longer reaches into infrastructure. The
+  singletons now live at the agent-tools frontier
+  (`alfred/agent/tools/filesystem.py`), where the LLM-facing wrappers
+  instantiate them once and thread them through. `analyze_release` no
+  longer needs the dirty `from ... import _KB` indirection. Tests
+  inject their own stubs by keyword (`prober=_StubProber(...)`) instead
+  of monkeypatching a module attribute.
+- **`ParsePath` enum renamed to `TokenizationRoute`.** The old name
+  collided with `pathlib.Path` in code-reading mental models, and was
+  one letter from `parse_path` (the field that holds the value) — making
+  it harder than it needed to be to spot the type vs the attribute.
+  ``TokenizationRoute`` says what it actually captures (DIRECT /
+  SANITIZED / AI = how the name reached the tokenizer), and the class
+  docstring now spells out the orthogonality with ``Road`` (EASY /
+  SHITTY / PATH_OF_PAIN, which captures parser confidence on
+  ``ParseReport``). The ``parse_path`` field name stays unchanged —
+  string values too — so YAML fixtures, the ``analyze_release`` tool
+  spec, and any external consumer are untouched.
+- **`enrich_from_probe` codec mappings moved to YAML.** The three
+  hard-coded module dicts (`_VIDEO_CODEC_MAP`, `_AUDIO_CODEC_MAP`,
+  `_CHANNEL_MAP`) translating ffprobe output to scene tokens
+  (`hevc → x265`, `eac3 → EAC3`, `8 → "7.1"`, …) now live in
+  `alfred/knowledge/release/probe_mappings.yaml` and are loaded into
+  `ReleaseKnowledge.probe_mappings` (new port field, populated by
+  `YamlReleaseKnowledge`). `enrich_from_probe` gains a third `kb`
+  parameter and reads the maps from there. Aligns with the CLAUDE.md
+  rule that lookup tables of domain knowledge belong in YAML, not in
+  Python — and opens the door to a future "learn new codec" pass.
+  Callers updated: `inspect_release`, `testing/recognize_folders_in_downloads.py`,
+  and all 22 sites in `tests/application/test_enrich_from_probe.py`.
+- **`ParsedRelease.tech_string` is now a derived `@property`**
+  (`alfred/domain/release/value_objects.py`). It computes
+  `quality.source.codec` joined by dots on every access, so it stays in
+  sync with the underlying fields by construction. The stored field is
+  gone from the dataclass, the dict returned by `assemble()` no longer
+  carries the key, `parse_release`'s malformed-name fallback drops the
+  `tech_string=""` kwarg, and `enrich_from_probe` no longer re-derives
+  it after filling `quality`/`source`/`codec`. Closes the
+  parser/enrichment double-source-of-truth that `e79ca46` had to fix
+  reactively. The fixtures runner now injects `tech_string` alongside
+  `is_season_pack` since `asdict()` skips properties.
 - **`RuleScope.level` is now an enum (`RuleScopeLevel`).** The set of
   valid levels (global, release_group, movie, show, season, episode)
   was documented only in a docstring comment and validated nowhere.
