thejayman77 ba74bbd5aa Snapshot: fog implementation + fidelity tooling baseline (pre bilinear-clamp fix)
Per-vertex GS fog end-to-end (gs_stub emit incl. persp_emit5, gs_prim_list_feeder
XYZ2->XYZF2 on PRIM.FGE, gs_make_sh3_scheduler_fixture.py F/FGE packing), new fog
TBs, fidelity attribution tooling. Functional baseline before removing the dead
bilinear lerp8 clamps (Codex: 161-node comb loop -> -0.042ns setup fail).

# Ch376 Audit Log - Seventeen-Draw Second-Palette Residency
- `zsrte17` extends Ch375 with three later, on-screen CBP `508` draws, producing a six-epoch
`fill, reuse, reuse, rebind, reuse, reuse` runtime-CLUT sequence at native 640x480.
- Local depth-4096 integration passes with 531,922 accepted fragments, 436,186 Z-pass updates, six fresh drains,
zero drops, exact Z `0/307200`, and exact color `0/132810`. Request-FIFO high-water is 2,090, 940, 1,757,
100, 81, and 84.
- On the DE25, both palette banks, both texture fills, all 934 expected records, and every drop gate pass.
- Board and traced integration framebuffers are byte-identical at SHA-256
`9101f42e3e575653a7e62c9dd5760fef69427b04cb45187e7a1697a5a0e0e864`.
- Replay-color is exact at `307200/307200`: 531,922 fragments, 436,186 Z-pass updates, 132,810 covered pixels,
and zero uncovered writes.
Ch376 closes the seventeen-draw second-palette residency expansion on silicon without RTL, constraint, or fit changes.
