Cutscene voice: resolve movies via continuous-stream cue regions

Cracked how the game maps a movie to its voice track and reimplemented it,
fixing wrong/short voices for RT and hokyu cutscenes.

## Mechanism (RE'd from a Canary file-I/O trace, user-confirmed by ear)

The movie voices are ONE continuous XMA stream, physically chunked into
`<lang>\Movie\VOICE_*.slb` (and `\etc\VOICE_D_*.slb`) sound.pak TOC entries
whose boundaries do NOT align with the cutscene cues. A single cue routinely
spans two `.slb` chunks, so a `.slb` does not necessarily hold the track its
name claims (they are off-by-one vs the cues). Each cue ends at an inline
trailer descriptor `(sound_id:u32be, 0x11, …)` whose id repeats at +0x800.

Resolution chain (all derivable on-disc, no guest-code RE):
  1. movie -> cue token         (ADVERTISE_MOVIE manifest VOICETRACK)
  2. cue token -> sound-id       (master sound registry, tables.pak
                                  a2c8c185=eng / b04238e0=jpn, schema 0x13cb84ba)
  3. sound-id -> [start,end)      scan the stream for trailer(id) and its
                                  predecessor; cue audio = the bytes between,
                                  read continuously across chunk boundaries.

Validated: decoded voice length matches each movie within ~0.4s, including
cross-boundary cues (ADV/RT01A/RT01B/RT01C/S00A/S01A + the 5 bound hokyu).

## Changes

- sylpheed-formats/src/movie_voice.rs (new): registry_voice_ids(),
  find_descriptor(), find_descriptor_before() (gap-tolerant predecessor).
  Unit-tested.
- viewer iso_loader.rs: resolve_movie_voice_region() + decode_voice_region()
  (continuous read via existing read_segment_range + to_xma_riffs). Voice/
  audio requests now region-first; a `\Movie\` token that fails region stays
  SILENT (never plays the wrong off-by-one chunk). Removed the old
  movie_is_demo_based suppress hack.
- Anchor tries subdirs Movie/etc/Voice so hokyu `\etc\VOICE_D_*` resolve too.
- Examples resolve_all/validate_cues/hokyu_final document + validate the pipeline.

## Status

- RT / S / ADV cutscene voices: CORRECT (user-confirmed).
- 5 manifest-bound hokyu (VOICE_D_450-454): CORRECT (user-confirmed).

## OPEN (handoff)

13 of 18 hokyu movies have NO manifest VOICETRACK; the game reuses the 5
recordings across stages via a code rule. `hokyu_fallback_token()` currently
guesses by category (ship LS/DS x source carrier-A/tanker-H: LS/A->450,
LS/H->453, DS/A->452, DS/H->454). USER REPORTS THIS IS SOMETIMES WRONG.
- LS/carrier has two takes (450 from s02A, 451 from s09A); the early-vs-late
  split is unknown — unbound LS/A currently all default to 450.
- Definitive fix = Canary `--phase_a_fileio_only` file.read trace of an unbound
  hokyu (e.g. hokyu_LS_s03A) to see which VOICE_D the game actually streams,
  then encode the real rule. Same method that cracked the RT mapping.

+//!      `S<NN>_SUPPLY_<ACROPOLIS|TANKER>`, in play order;
+//!   2. the **value RECORDS**, in the same order — each a run led by `<movie>.wmv`

+//!      `<pak>+SUBTITLE_<movie>.tbl` (field `SUBTITLE`), and a `VOICE_<token>`
+//!      (field `VOICETRACK`). A few slot keys are **valueless** (e.g. stages 5 and
+//!      12 have no resupply video) — those slots have no record and are skipped.
 //!
-//! We read the manifest by grouping the string pool on `.wmv` (the pool is
-//! emitted in the same order as the records), which is robust without decoding
-//! the `IDXD` record structure.
+//! The **slot key is the semantic role** — this is how the game separates a
+//! cutscene voice from in-mission radio chatter (structurally, by which slot/bank,
+//! not one boolean): `MS*` = story intro (`VOICE_S*`), `STAGE*_PHASE*` = radio-box
+//! cutscene (`VOICE_RT*`), `S*_SUPPLY_*` = resupply (`VOICE_D_45x` or none).
+//! Resupply videos are **reused across stages** (`S04_SUPPLY_ACROPOLIS` →
+//! `hokyu_DS_s02A`), so the mapping is genuinely a table, not derivable from names.
+//!
+//! The voice token is likewise **not** always `VOICE_<movie>`: most movies use
+//! `VOICE_<movie>` (in `<lang>\Movie\`), but the resupply cutscenes bind to
+//! in-mission radio clips like `VOICE_D_450` (in `<lang>\etc\`), and some have no
+//! voice at all. This manifest is the ground truth.
+//!
+//! ## Alignment
+//!
+//! Slot keys and value records would be a 1:1 positional zip but for the valueless
+//! slots. We recover the gaps without decoding the binary node/index region by
+//! using the fully-derivable **`MS<NN><X>` → `S<NN><X>` anchors**: a non-`MS` slot
+//! whose record would be an `MS` target actually belongs to the upcoming `MS`
+//! slot, so the non-`MS` slot is a gap. (Decoding the node region would make this
+//! exact and also unlock the defaulted numeric fields in other IDXD tables.)
