Fix championship mode progression (win recorded as loss)

[jessetbh]

Fixes #1.

Symptom

In championship/story mode, every match was recorded as a loss regardless of the actual result — no prize money, and the story advanced down the failure branch. Confirmed on World Heavyweight and IC titles (matches the issue report; reproduced on Windows).

Root cause

A novel N64Recomp miscompile. The storyline-condition evaluator func_800EE1F0 dispatches through a jump table at 0x801036D0 that is indexed by a loop-carried induction pointer ($s2: base set once above the loop, +4 per iteration on the back-edge). With no in-block sll idx,2 for N64Recomp to pattern-match, it emitted a constant index (jr_addend = 0) — the only non-register addend in the whole build — collapsing the 5-way switch to case 0. The per-slot mask sequence {0x7, 0x3000, 0x70, 0xF00, 0x70000} degenerated to all 0x7, so the win condition could never match and the evaluator returned the lose/default node.

fix_switches does not catch this: the table is fully present; only the index is wrong.

Fix

New post-regen pipeline step tools/fix_jraddend.py. It detects the jr_addend_* = 0 signature and rewrites it to (uint32_t)ctx->rD - <table_base>, so the live induction pointer drives the dispatch. The (uint32_t) cast is required — the guest pointer is sign-extended to 64 bits, and a zero-extended base subtraction would overflow the switch into switch_error (that failure mode was hit and corrected during bring-up). Idempotent; fails loud. Registered after fix_switches in BUILDING.md, validate.yml, and the PR template.

The generated RecompiledFuncs/ is gitignored, so the fix ships as the tool — CI regenerates and applies fix_jraddend during the build. This PR's CI run exercises exactly that path.

Testing

• Rebuilt locally; the evaluator now selects the correct masks (index 0–4 verified across the full range).
• Played a championship match to a win: money awarded and the win storyline path taken (previously: crash after an interim broken revision, then correct after the cast fix).

Also

• Bumps version to 0.1.1 for the patch release.
• The same tool was ported to the sister repos as defense-in-depth (separate; all reported 0 affected sites — No Mercy was the only game hit).
