Re-shape MemoryAccess so write methods take &self and rely on interior
mutability (atomics in GuestMemory, Cell in test mocks). This unblocks
the &Arc<KernelState>-only execution model the CPU/HLE crates moved to.
GuestMemory grows: per-4 KiB-page write-version counter (page_version)
that the CPU's decode cache and the texture cache observe via Acquire,
fenced 32-bit/64-bit read/write helpers (Release on writer / Acquire on
reader) that PM4_EVENT_WRITE_SHD and the matching CPU consumers use to
synchronize fence publication, and broader page-table / heap accounting
needed by the new HLE allocators.

Workspace gains a new xenia-ui member that owns the winit/wgpu
window, the Xenos display pipeline (xenos_pipeline + render +
texture_cache_host), HUD font/blit shaders, and the input-bridge
plumbing the app uses to surface guest framebuffers and overlays.
Workspace dependencies grow accordingly: rusqlite is replaced with
duckdb (analysis pipeline now writes DuckDB stores), and tracing /
metrics / pprof / winit / wgpu / gilrs / pollster / crossbeam /
bytemuck are added at workspace level so xenia-ui and xenia-app
share versions. Cargo.lock regenerated.

Rust reimplementation of the xenia Xbox 360 emulator targeting reverse-
engineering and preservation, initially scoped to Project Sylpheed.
Includes:
- XEX2 loader (LZX decompression, AES decryption, PE parsing)
- XISO / XGD2 disc image VFS
- PPC interpreter with 200+ opcodes and VMX128 decoding
- Static analyzer: functions, cross-references, labels, asm + SQLite output
- HLE kernel covering the xboxkrnl/xam subset used by Sylpheed init
- Debugger with in-memory and SQLite-backed execution tracing
- `xenia-rs` CLI with extract/dis/exec commands that produce cumulative,
superset SQLite databases and opt-in instruction/import/branch traces
