thePR0M3TH3ANandClaude Opus 4.8 35c4e68cde chore(perf): add nip-07/relay diagnostic harnesses + dev REQ monitor
Headless Playwright probes that reproduce the real login path via a fake
window.nostr extension (which loginWithNsec bypasses) and measure
steady-state extension-call and relay-REQ rates:
- nip07-heat.mjs, req-capture.mjs, ws-lifecycle.mjs, loopc-capture.mjs, etc.

Plus js/devReqMonitor.js: a localhost-only WebSocket REQ-rate monitor that
warns in-console when relay traffic spikes, naming the storming kinds — used
to capture the real-environment storm the mock-relay harness could not see.
Removable once the refactor lands.
