docs(examples): add the CMS proof-of-concept dogfooding artifact
A WordPress-inspired CMS whose entire backend is PiCloud Rhai scripts
deployed with pic apply, plus a SvelteKit frontend. Built to dogfood the
project tool, CLI, and SDK; exercises docs/kv/files/users, docs+queue+cron
+pubsub triggers, the transactional-outbox notification chain, a docs
before-interceptor, set_if CAS, SSE, per-app CORS, env overlays, and a
durable Workflow (validate -> enrich || seo -> publish -> finalize) started
with workflow::start and polled with workflow::run_status, visualized live
with Svelte Flow.

FINDINGS.md / SECURITY.md capture every gap, surprise, and security issue
found (each tagged [PiCloud] vs [CMS]); the platform fixes for the
actionable ones ship in the preceding commit.

Also folds in the read-only `pic` allowlist entries added to
.claude/settings.json during the session (fewer-permission-prompts).
