S00-003: Approve bounded XMPP selection after independent WSS and SCRAM checks

Changes: Accept ADR 0002 for pinned Stanza with mandatory bounded transport, verified SASL and SHA512 composition; record independent review findings and handoff with external limits retained.
Validation: Fresh-cache pinned npm ci and browser build succeeded; all 112 tests passed. Verified 51 locked entries, 26 installed notices and 340 unchanged vendor files; six offer permutations and six adversarial XML checks passed; make check passed 72 tooling tests. No actual browser, independent full XMPP server/client, OMEMO or release readiness acceptance.

+Reviewer auto-qa-d49749753ac6, 2026-10-15: accepted bounded S00-003 and ADR 0002.
+Fresh-cache pinned npm ci, browser bundle and 112 tests, dependency/notices/vendor
+checks and make check (72 tooling tests) passed. Six additional offer permutations
+and six adversarial XML inputs passed independent assertions. Review evidence:
+state/evidence/S00-003-review.md. All documented external/browser/interoperability/
+crypto/timing/lifecycle/aggregate-resource limits remain. Future adapters must
+install the three required seams before connect and construct deliberate outbound
+body projections. Coordinator must commit review before any next fresh session;
+reviewer exits on approve without Git mutation or another task/agent launch.
