- Add Prometheus counters/gauges/histograms: messages_total{source},
message_bytes_total, active_subscribers, publish_duration_seconds.
- Add /api/signal/<room> mailbox endpoint (POST adds, GET drains).
Currently scaffolding for WebRTC SDP/ICE exchange — peers do not
use it yet; client-side WebRTC negotiation is roadmap.
client: structured default label
Use "<GOOS>-sse-<role>" (e.g., windows-sse-listener) instead of the
old "linux-client" fallback. -label still overrides.

Single Go module with two binaries (server, client) and an embedded
phone UI. MVP transport is HTTP POST → SSE fanout; the roadmap calls
for upgrading to WebRTC P2P with Sign in with Apple for identity, mDNS
for discovery, and OS clipboard hooks.
- server/: Go HTTP server, embedded index.html, broadcast bus with
short replay history, SSE stream endpoint, single-binary deploy.
- client/: subscribes to SSE feed and prints messages; -send for
one-shot publish from CLI. No OS clipboard touched yet (v0.5).
- web/index.html: dark phone-first UI, paste-clipboard button (uses
navigator.clipboard.readText), live feed of incoming messages via
EventSource.
This commit is intentionally tiny — it proves the end-to-end shape so
the WebRTC/SiwA/mDNS pieces can be added incrementally without
restructuring.
