feat: ContextVM (MCP over Nostr) server with WS masking fix

- Full CVM server: persistent WS relay listener, kind 25910 subscription
- MCP protocol handlers: initialize, tools/list, tools/call, ping
- 10 MCP tools: get_config, set_config, get_balance, wallet_send,
  get_sessions, get_usage, set_payout, set_metric, set_price, wallet_melt
- CEP-6 announcements via WS (kinds 11316, 11317, 10002)
- Auth check: owner npub only
- Fix: WebSocket client-to-server frame masking (RFC 6455 requirement)
- Fix: Raw event JSON in EVENT wrapper (no re-parsing that breaks sig)
- SNTP init after STA gets IP
- 282 unit tests passing (61 CVM + 60 MCP handler + 161 existing)
- Integration test scaffold: tests/integration/test-cvm.mjs
