v0.1: HTTP+SSE broadcast bus + phone web UI + Linux client
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.
