docs(web): refresh demos copy for v2.2 (JSON-RPC, capabilities, SSE)

Update the /demos landing page text to reflect v2.2 protocol surface:
- Hero: highlight JSON-RPC 2.0, version negotiation, scoped capabilities
  and streaming responses over WebSockets or SSE.
- Demo 1 (.process): describe POST /asap envelope and ASAP-Version header.
- Demo 2 (Schema): mention capability schemas with constraint operators
  (max, min, in, not_in).
- Demo 3 (Memory): cover both WebSocket memory_snapshot events and
  TaskStream chunks via POST /asap/stream (Server-Sent Events).
- CTA: remove inaccurate "TypeScript" SDK claim; mention reference
  integrations (LangChain, CrewAI, PydanticAI, LlamaIndex).

No structural/code changes; preserves existing CTA hyperlinks
(verified: GitHub examples 200 OK, /browse route exists).
