fix: audit batch — MCP timeouts, entryPost, vip_audit 404s, and 6 more (#824)

* fix: 9 unaddressed log-audit / run-audit findings

Co-authored-by: Cursor <cursoragent@cursor.com>

#815 entryPost stdlib-only imports; #823 MCP timeoutMs on checkout_pr/shell;
#816 FREE_FALLBACK → opencode/big-pickle; #822 chunk GraphQL nodes ≤100;
#817/#821 vip_audit 404 skip paths; #813 longer serializable retries;
#818 run-context handler-entered log; #805 audit severity template.

* fix: update footer test for big-pickle fallback slug

* fix: anneal round 1 — ghaCore getState casing, post-hook timeout

Match @actions/core STATE_ key semantics (no uppercasing), cap
postApiFetch at 30s, trim serializable retries to stay under GitHub's
10s webhook window, log Clerk failures in getUserTokenByGithubLogin.

* revert: drop run-context handler log (#818 deferred)

The #692 client-side fix is already on main; residual SyntaxError hits
are old action pins. Per-request log added noise without fixing anything.

* document per-issue Closes syntax for audit PRs

GitHub only auto-closes the first issue when numbers are comma-separated;
/audits and AGENTS.md now require Closes before each issue number.

* fix: anneal round 2 — outreach privacy, alert resilience, vertex cleanup

Filter private repos from VIP authority output, harden console alert
lines against DB failures, drop spoofable changesets body check, and
unset GOOGLE_APPLICATION_CREDENTIALS after vertex credential cleanup.

* refactor: drop codexHome re-export of detectCodexRefresh

Import detectCodexRefresh directly from codexRefreshDetect.ts everywhere;
rename the unit test file to match. codexHome.ts stays install-only.

* fix: drop deprecated minimax-m2.5-free; add paid minimax-m2.5

Remove the deprecated free MiniMax promo from the catalog, docs, and
tests. BYOK fallback and picker copy stay on opencode/big-pickle. Add
opencode/minimax-m2.5 and openrouter/minimax-m2.5 for Zen BYOK and
Router. Pin #816 regressions with freeFallbackCatalog and runErrorRenderer
unit tests.

* fix: hidden minimax-m2.5-free fallback for stored slugs

Re-add opencode/minimax-m2.5-free as a hidden fallback alias to big-pickle
so repos with the legacy slug still resolve as free. Drop live Zen API
experiment tests in freeFallbackCatalog.test.ts.
