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

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.
