chore: correct the review agents' briefs and add a Phase 5 minifier check

Separated from the step 1 feature commit on adversarial-reviewer's own
recommendation: instructions that narrow a reviewer's scope should not
travel in the same commit as the work that reviewer is checking.

claims-auditor.md — REMOVE the enumerated membership list. It read
"ADRIC, ADRIO, OBA sections only" while AGENTS.md §4 had gained the
Canadian Tax Foundation that morning, so the auditor's own brief
contradicted the register: it would have flagged a verified membership
as unverified and would not have noticed CTF being dropped. This file
has now hosted a stale claim twice. Replaced with an instruction to
read the §4 row at audit time — a copy of a fact goes stale where
nobody re-reads it.

adversarial-reviewer.md — state that Lighthouse cannot be run until
step 7 and that its absence is not a finding (AGENTS.md §7, R11).
Repair a sentence left truncated mid-list. Caveat the "~1 MB of logo
PNGs" figure against Q34, which is open on it.

build.md — Phase 4 now carries the measurement that justifies the
re-review requirement: on the Astro 5→7 upgrade four of six
second-round findings were defects in the first round's own fixes.
Phase 5 gains a grep asserting no `animation` shorthand beside
`animation-timeline` survives into dist — Lightning CSS folds them
into an invalid declaration that works in dev and is dead in the
build. That happened twice in one session, the second time inside the
fix for the first.
