Room-based SFU relay:
- Clients join named rooms (room name from QUIC SNI)
- Each participant's packets forwarded to all others (no mixing)
- Multiple rooms run concurrently on one relay
- Web bridge passes room name from URL path to relay
Push-to-talk (radio mode):
- Toggle "Radio mode" checkbox after connecting
- Hold PTT button or spacebar to transmit
- Release to mute mic (receive-only)
- Works on desktop (spacebar) and mobile (touch)
URL routing:
- /myroom → joins room "myroom"
- Room name input field as fallback

Bridge mode rewrite:
- First client echoes while waiting, checks every 100ms if paired
- Second client triggers bridge immediately, first exits echo loop
- After bridge ends, slot is cleared for the next pair
- No more two tasks competing for the same transport recv
Web client auto-reconnect:
- On WebSocket close/error, automatically reconnects after 1s
- Keeps retrying as long as the user hasn't clicked Disconnect
Test fix:
- Install rustls crypto provider in transport config tests
(fixes race condition when running full workspace tests)

- Use power-of-2 buffer (1024) for ScriptProcessorNode
- Accumulate samples and send exact 960-sample frames
- Remove unused watch import from relay

When no --remote is configured, the relay now operates in bridge mode:
- First client connects → echoes while waiting for a peer
- Second client connects → both clients are bridged bidirectionally
- A's packets go to B, B's packets go to A
- Stats logged every 5 seconds (a_to_b / b_to_a packet counts)
- Falls back to echo if only one client connects
This enables the core use case: two clients on different networks
calling each other through a single relay.

- --record now handles Ctrl+C: saves PCM file before exiting
- Relay without --remote runs in echo mode (loops packets back to sender)
instead of sink mode, enabling single-relay audio testing
- recv task returns collected PCM via channel for clean file write
