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.
