[pending-judge] fix(r4): audit contract, subdomain forwarding, timeout kill (judge r3 blockers)

BLOCK0: catalog deploy audit now uses the REAL AuditLogger contract
(auditLogger.log({action,resource,details,outcome,ip})) fire-and-forget
via Promise.resolve().catch — async audit failures can never fail the
deploy response (tested with a throwing audit backend).
BLOCK1: verify.sh targeted-jest block captures jest exit code explicitly
(set +e / rc / loud FAIL) — no silent termination under set -e.
BLOCK2: subdomain advertised by the App Selector modal is now FORWARDED
end-to-end (selector -> /deploys/catalog/deploy validated charset ->
bridge --subdomain -> CLI CatalogInstallOptions, implemented in
dc-catalog-2 r3); invalid subdomains 400 before the bridge (4 cases).
POLISH: boot-timeout SIGKILLs the child (no leaked process).
New r4 suite: 7 tests (audit shape success/failure, subdomain forward +
4 rejections). Full suite 157 suites / 3519 tests green.
