bone_sse: assembly-verified reimplementation of transformMatrix4x4
...
13 bugs fixed by comparing against full assembly dump (5317 instructions):
- Emitter check: this+0x188 -> this+0x1D8
- Animation time: added FILD*time_scale pattern for both primary (+0xB0)
and secondary (+0xDC) slots
- Conditional multiply: bone_local *= *(bone_rt+0xF0) was missing
- Billboard post-processing: 4 switch cases (types 8/16/32/64) implemented
- Color animation loop bound: model_hdr+0x64 -> +0x6C
- Bone keyframe data stride: 0x24 -> 0x54
- Ribbon emitter output stride: 0x15C -> 0x170
- Particle data/output strides: 0x1FC/0x17C -> 0x1F8/0x16C
- Child SceneObject offsets: attach_idx +0x184->+0x1D4, next +0x190->+0x1E4
- Root bone parent: identity -> this+0xFC
New files:
- BONE_SSE_PROGRESS.md: section-by-section verification status
- t44_full_asm.txt: complete function assembly (ground truth)
- t44_helpers_asm.txt: all 12 helper function assemblies
- math_sse.zig: 18 x87->SSE polyfill stubs (VanillaFixes integration)
Also: OnWorldUpdate hook for true per-frame counting, DUMP_FRAMES=450.
SSE dispatch currently disabled while particle sections are being verified.

Add glyph shadow cache: direct-mapped O(1) bypass for game's 4-bucket hash table
...
GetOrCreateCharacterGlyph (0x5ca2d0) is the #2 CPU hotspot at 3.65%.
The game's glyph cache uses only 4 hash buckets for ~95 ASCII chars,
causing ~24-entry chain walks with pointer chasing on every lookup.
Text measurement (99.8% of calls) re-walks these chains per character,
thousands of times per frame during UI updates.
Shadow cache: 4096-entry direct-mapped array with Murmur2 hash,
keyed on (FontObject*, charCode, param2). Cache hit returns the
cached float width via FPU ST(0) inline asm, skipping the chain
walk entirely. Gated behind ab_use_custom for A/B benchmarking.

Add render pipeline profiling: 5 hooks across render/movement path
...
Hooks executeSceneRenderPass (0x708900), renderFrame (0x707680),
transformMatrix4x4 (0x714260), RenderTextureQuads (0x76FB00), and
CMovement::ProcessUnitMovementUpdate (0x616620).
Unified stats dump every 180 render passes shows per-frame call counts,
cycle costs, bone counts, recursion depth, and quad item counts.

plus the full 2263-line main function decompilation.
