b5a193839c port: make the Godot menu shell the agent's primary objective
Sets a new mission: boot the real disc through developer splash -> intro video
-> title -> main menu -> submenus in Godot 4, interactively, with no gameplay,
no 3D and no emulator.

docs/port/MISSION.md defines it -- eight gated milestones, each finished by an
ARTIFACT rather than by compiling, plus the Ready Room as an explicitly gated
stretch goal with a one-iteration probe that decides go/no-go. GP_READY_ROOM is
1106 entries with 6 recoverable names and is ISL-scripted, so it is either a
week or a quarter, and the agent must not start it on its own authority.

Architecture, per the user's decision: the Godot project is INDEPENDENT of the
Rust viewer and never reads a disc format. An offline Rust exporter converts the
disc into open formats; Godot reads only those. No GDExtension, no Rust in the
Godot project, and sylpheed-viewer is off limits -- it stays the human's
verification tool with its static-data rule intact.

docs/port/FORMAT.md specifies the open format, versioned, because modding is the
port's second goal and that makes the layout a deliverable rather than a temp
directory: JSON over XML (Godot parses JSON natively; its XMLParser is SAX),
names never hashes, provenance in every generated file, and unknowns listed
rather than guessed.

The discipline the whole thing rests on is the derived/authored split. `export/`
is regenerated wholesale and never hand-edited; `authored/` is hand-written and
survives a re-export. Three things this milestone needs are NOT on the disc in
any decoded form -- which button does what, paint order, and menu sound cues --
so they live in `authored/` with a stated `why`. Deleting an authored entry
because the exporter can now emit it IS the measure of progress.

`export/` is gitignored: it is generated from the user's own disc and this stays
a clean-room repo.

Container: adds a pinned Godot 4 (windowed under Xvfb for screenshots, plus a
headless wrapper). ffmpeg already carries libtheora, which is the video target --
Godot 4 plays only Ogg Theora natively and the disc's ADV.wmv is WMV3/WMA Pro.

9daac6f1f0 re: read the defaulted weapon stats out of live guest memory
Canary backs the whole guest address space with one shared-memory file, so the
game's RAM is readable from the host while it runs -- no debugger, no emulator
patch. That turns the parked Route-B question (fields the IDXD omits because
they sit at their default) from "unreachable" into a table lookup.

gmem.py maps guest VAs into /dev/shm/xenia_memory_* via Xenia's fixed table and
searches only the allocated extents, so a full-RAM scan is ~0.2 s.

weapon_runtime.py finds the parsed objects by scanning for their vtable, then
*solves* the struct layout instead of guessing it: every (field, offset,
encoding) triple is scored against the disc records, and a binding is accepted
only with zero contradictions -- and marked confirmed only when >=10 records
agree on >=3 distinct values, because a field whose samples are all one number
matches any offset holding that constant.

Result: Weapon (0xc0) and Shell (0x200) mapped, 4393 values the disc does not
carry, for all 126 weapons at 5 % save progress. Cross-checks hold -- the
Arsenal DATA SHEET read 4 for wep_05/wep_60 Max. Lock Ons and the memory read
agrees; the in-flight HUD's 06000/00300 match LoadingCount; all 252 objects are
byte-identical across a screen change, so this is definition data, not state.

Two findings fell out: `IsCharging = Yes` switches LoadingCount and
TriggerShotCount to float32 (it partitions the 8 float-encoded records exactly),
and two .tbl entries declare Shell_TCAF_Ship_AAGun with conflicting Power -- the
runtime keeps the one that omits it.

Where the defaulted values *come from* (the IDXD's undecoded binary node region
vs code defaults) is not settled here; they vary per weapon, so they are not one
constructor constant.

f8127e73b0 feat: initialise workspace — Milestone 1 asset explorer
Three-crate Cargo workspace structured per PROJECT.md spec:
- crates/sylpheed-formats  — Xbox 360 format parsers (no Bevy)
- crates/sylpheed-viewer   — Bevy 0.15 asset viewer + egui UI
- crates/sylpheed-cli      — CLI tools (extract/list/sniff/texture)

Milestone 1 features:
- XISO disc image reading via xdvdfs 0.8
- XPR2 texture container parsing + Morton de-tiling
- D3DFORMAT → wgpu TextureFormat mapping (DXT1/3/5, DXN, ARGB)
- Custom Bevy AssetLoader for .xpr files
- Orbit camera (LMB orbit, RMB pan, scroll zoom)
- egui file browser + RE notes panel
- CLI: extract / list / sniff / texture info / texture export
- GitHub Actions CI (Linux, macOS, Windows, WASM)
- Trunk WASM build config
