Portal v0.1.1 — loopback clarification + trending-demo rename

Additive clarifications over v0.1.0. Every v0.1.0-conformant portal remains v0.1.1-conformant.

Spec changes

• call_endpoint loopback exception. http://localhost and http://127.0.0.1 are now explicitly permitted (local development). Production still requires https://. Both the JSON Schema pattern and the lean validator's URL regex updated together.
• New vector: MV-11-loopback-http covers the exception.
• Rate-limit appendix (B): SHOULD-level defaults + Retry-After header semantics for the RATE_LIMITED error code.
• Runner API: adds validateAgainstVectors(manifest) for offline full-suite reporting. runConformance() renamed to runSmokeConformance() for clarity.

Reference rename

reference/star-screener/ → reference/trending-demo/.

Preserved: the human-facing service name "Star Screener" (appears in manifests, terminal demos, directory entries).
Replaced: the kebab-case package/filesystem slug. pnpm --filter trending-demo start now runs the demo.

Version bumps

• @visitportal/spec 0.1.0 → 0.1.1
• @visitportal/visit 0.1.0 → 0.1.1 (no API changes; version tracks spec)
• @visitportal/cli 0.1.0 → 0.1.1 (no API changes)

Numbers still hold
