feat(builder)!: remove deprecated SSE transport - Streamable HTTP only (2.0.0)

BREAKING CHANGE: GET /sse and POST /messages now answer 404. Every client
connects over Streamable HTTP at /mcp. The sse remote is removed from
server.json.

- Add unauthenticated GET /health ({status, version}); no session, no
  rate-limit touch.
- Add any-origin CORS across the whole HTTP surface, incl. OPTIONS
  preflight and error responses; mcp-session-id exposed to browsers.
- Unify every version string at 2.0.0; both McpServer identities now read
  the version from package.json at build time instead of hardcoding it.
- Raise @modelcontextprotocol/sdk floor to ^1.30.0 and sync the local
  install with the lockfile.
- Tests: retire the SSE-shaped auth-gating suite (its unique
  process-liveness test is ported to streamable-http-gating), move the
  shared harness and rate-limit suite to StreamableHTTPClientTransport,
  and add http-surface.test.ts for CORS//health//sse-404 coverage.
