chore(audit): mark P7 frozen-snapshot drift cleared (manual regen, no code change)

Browse Source 
P7 of the PPC instruction audit fix application: re-ran the
ppc-manual generator (`python3 ppc-manual/generator/generate_manual.py`)
to regenerate all 350 family pages from current xenia-rs and
xenia-canary source. The 3 audit-cited stale snapshots
(PPCBUG-066/117/145) are now refreshed.

Note: the `ppc-manual/` directory is not versioned in xenia-rs/.git,
so this commit is purely the audit-findings status update + report
section. The regen itself happened in-place outside this repo.

Verification: post-regen grep confirms the old "For now, just trace
and continue" stub is gone from every page, and modern constructs
(trap::evaluate, current reservation_line model) appear correctly.

### P7 — Frozen-snapshot drift sweep (2026-05-02, manual regen — no xenia-rs code change)
**PPCBUGs fixed**: 3 IDs.
- PPCBUG-066: ppc-manual/branch/{td,tdi,tw,twi}.md — old unconditional-trap stub replaced with current TO-field-evaluating implementation snippet.
- PPCBUG-117: ppc-manual/memory/ldarx.md — refreshed to current reservation_line/reservation_table model.
- PPCBUG-145: ppc-manual/memory/stwcx.md — same reservation refresh.
**Methodology**: ran `python3 ppc-manual/generator/generate_manual.py` (the existing idempotent generator that scrapes xenia-rs and xenia-canary source for each opcode and emits a Markdown page). Output: 350 family pages updated, 598-key index.json refreshed.
**Verification**: post-regen `grep` confirms (a) the old "For now, just trace and continue" stub is gone from every page; (b) modern constructs (`trap::evaluate`, the current reservation pattern) appear in the trap and reservation pages.
**Note on scope**: the `ppc-manual/` directory is not versioned in `xenia-rs/.git`. The regen is therefore "done by running the script" with no commit landing in this repo. Documented for posterity here.
**Implicit drift cleared by earlier phases**: addicx (PPCBUG-003 fixed in P4), andisx (PPCBUG-023 fixed in P4), cmp/cmpi (PPCBUG-050 — no code change required; manual snapshot now reflects current behavior), extsbx/extshx (PPCBUG-036/037 fixed in P4 batch 2), 32 in batch 1 — all auto-resolved by re-running the generator after P1-P6.
**Conclusion**: P7 is functionally complete. No xenia-rs code change. Next: P8 — test gap closure.
