runtime_root() fell back to /tmp, which does not exist on Android/Termux, so the
daemon's control.sock would land in an unwritable path. Fall back
XDG_RUNTIME_DIR -> TMPDIR -> /tmp; Termux sets TMPDIR to $PREFIX/tmp. No change
on a normal box (TMPDIR is typically unset there). Enables the Phase 1
join/read/say socket to work on-device.

Invert the agent model: a headless OperatorBridge(Client) owns the
websocket while a Claude Code session drives it via a unix control
socket. Reuses Client SRP/Fernet and AgentBridge's reconnect/serve
shape. Ships an hh-bridge CLI (up/read/say/roster/status/down) with a
seq'd in-RAM inbox + asyncio.Condition long-poll (read --wait) for
in-turn autonomy. ACL/sandbox-status frames are recorded for later
phases. Sandbox drive, delegation and nesting are out of scope here.
