S00-002: Propose a pinned React stack with a reproducible rendering spike

Changes: Compare React and Vue in ADR 0001; pin React 19.3.1, TypeScript 7.0.2, Vite 8.3.4 and Node 24.21.0/npm 11.19.0. Add isolated TSX counter, exact lockfile, runtime/TLS guards, reproduction instructions and license inventory/runtime notices. Preserve the reviewed registry probe and leave ADR proposed for security review.
Validation: Clean npm ci with a fresh cache and npm run build passed on the pinned tools; strict typechecking and repeated local build hashes matched. HTTP preview served HTML and matching JS. make check passed all 66 tooling tests; git diff --check passed. Browser interaction was unavailable and is recorded as an external check; no app, crypto/protocol interoperability or release readiness is claimed.
