docs: align hardening + driver docs with Hono-only adapters (#2392, 12.0)

Follow-up to the adapter trim (#2391). Hand-written docs only (ADRs / audits /
CHANGELOGs left as historical):
- docs/HARDENING.md: Fastify recipe → Hono recipe (the @objectstack/fastify
  import was broken after removal); CSRF → hono/csrf; CORS → createHonoApp.
- docs/design/driver-turso.md: drop plugin-msw row; "all adapters" → Hono.
- packages/plugins/driver-memory/README.md: drop plugin-msw bullets.
- packages/runtime/README.md: framework examples narrowed to Hono.
- docs/launch-readiness.md: stale express/fastify residual note → Hono.

Verified: no removed-package refs remain in current docs.

+docs: align hardening / driver docs with the Hono-only adapter surface (12.0)
+
+Follow-up to the adapter trim (#2391): the hardening guide's rate-limit/CORS
+recipes are rewritten from Fastify to **Hono** (the shipped adapter; the old
+`@objectstack/fastify` import was broken), CSRF guidance points at `hono/csrf`,
+and stale `@objectstack/plugin-msw` references are dropped from the driver-memory
+and driver-turso docs. README framework lists narrowed to Hono.
