- WebSocket sends HTML fragments with id="price-display" instead of JSON
for direct HTMX OOB swap on the client
- Switch from ring-undertow-adapter ws wrapper to raw Undertow WebSocket
API (proxy) to fix single-connection limitation
- Keep JSON endpoint at /api/price/latest unchanged
- Update CLAUDE.md and README.md

- Replace SSE endpoint (/api/price/stream) with WebSocket (/api/price/ws)
using ring-undertow-adapter's built-in WebSocket support
- Change Docker internal port from 4100 to 4101 to avoid conflicts with
local dev (make run still uses 4100)
- Add free-port.sh utility script

Use Undertow dispatch for SSE handler to avoid Ring adapter conflict.
Add docker-compose.yml (port 4101 to coexist with local dev on 4100).

Split from btcprice monolith. Owns DB, migrations, Binance WebSocket,
Kraken OHLC pollers, and exposes a JSON API with SSE price stream.
