Resolve call-script dispatch: id = raw SYS4INI file index

Native-RE (Ghidra) cracked call-script <id> (opcode 0x03): its handler
FUN_0041bc90 -> loader FUN_0040e980 -> resolver FUN_0044f390 indexes an
80-byte record table at base + id*0x50 == the SYS4INI record layout. So
`call-script <id>` is a direct RAW index into the SYS4INI global file
table (the asset index we already parse) -- there is no separate on-disk
id->code registry. This resolves name-resolution.md #1, statically, no
Frida.

Confirmed: all 297 distinct corpus call-script ids resolve to a .BIN
script with a semantically-exact name (0x1ab->ADDITEM, 0x2ae7->MES,
0x143->BUNKI, 0x329d->CALCREVISE), 0 out-of-range, 0 alternate-pack.
Companion op 0x8f `call` is an intra-script JSR (FUN_0041fba0), not
cross-script.

- parse_sys4ini.py: preserve `raw_index` per entry (= the engine file id;
  index the RAW records incl. '@' placeholders) + emit
  build/callscript-names.json (id->name).
- sys4load.py: annotate `call-script 0x1ab =ADDITEM.BIN`.
- opcodes.toml 0x03/0x8f refined (source=investigation, confidence high,
  handler VAs) + rebuilt opcode-reference.md.
- docs: engine-re.md (op 0x03 section + backlog re-aimed),
  name-resolution.md #1 (SOLVED), script-inventory.md (call graph +
  living-reference decision), tools-reference.md.

feat(assets): solve asset resolution (SYS4INI per-scene section manifest)

resId -> files[section_base(scene) + resId]. SYS4INI's file list is
sectioned, one per scene (SCxxxx.BIN + its cross-archive asset manifest);
file_number is the index within the section. Unified for set-texture,
play-bgm, play-voice. Fully static/general -> no per-scene capture.

- tools/parse_sys4ini.py: SYS4INI (S4IC422, LZSS) -> build/asset-index.json
- tools/resolve_asset.py: sections + (scene,resId) resolver -> build/asset-sections.json
- validated: 97% structural, SC0000 17/17 vs Frida, 586/595 captured loads
- opcodes.toml: set-texture/create/draw-texture, play-bgm/voice enriched (frida-grounded)
- Frida tooling (capture_load_order all-archive, correlate_scope, ...) + vm0 --settex
- docs: asset-resolution-re (step2 SOLVED), global-memory-re (shelved), tools-reference
