feat(a2b): asset-RE tooling + findings; render blocked on asset resolution

Browse Source 
- tools/convert_agf.py (AGF->BMP stills), tools/frida/ (capture harness + README; Frida 17.15.3)
- docs/asset-resolution-re.md: foundational RE steering doc (resId->file; graphics+audio; not
  machine-verifiable -> Frida ground truth + human oracle). RE plan: parse SYS4INI, crack resId->name,
  backend render (A2b plan Tasks 3-5), audio, movies.
- Finding: SC0000 bg = slot-0 slideshow (res 0x23 first); resolution opaque (CGINIT not a name map,
  SYS4INI S4IC needs RE, Frida file-I/O noisy/memory-mapped, opening mixes MPEG movies).
- slice plan updated; texture ops already engine-driven (Task 1, prior commit).

**Next = A2b:** background via `AGF2BMP2AGF.exe`, `play-voice`/`play-bgm`, choices → VM globals,
just-enough `call-script`/state (unlocks richer scenes).
### A2b-Background — machinery landed; render blocked on asset resolution (2026-07-06)
Engine-driven texture ops shipped: `create/set/draw-texture` (0x1f8/0x1f9/0x1fb) promoted from VM stubs
to typed `IHost` methods (CaptureHost no-ops → trace parity kept; engine tests 8/8). Tools: `convert_agf.py`
(AGF→BMP stills) + `tools/frida/` capture harness (Frida 17.15.3 installed). **Blocked:** rendering the bg
needs `resId → asset file` resolution, which proved opaque — CGINIT isn't a filename map, SYS4INI (S4IC422)
needs format RE, Frida file-I/O offsets are noisy (memory-mapping), and the opening mixes movies (MVB/OP =
MPEG) with stills so eyeball-curation stalled too. **Asset resolution promoted to a dedicated foundational
RE effort** (graphics + audio; not machine-verifiable — Frida ground truth + human eye/ear are the oracle):
see `docs/asset-resolution-re.md`. The backend render (ResourceMap + Godot compositing) stays designed in
`docs/superpowers/plans/2026-07-06-a2b-background.md` Tasks 3–5, mechanical once resolution lands.
