release: v0.0.1-16 — one binary, a wall of hosts, and a one-run handoff

One binary, `mux`, and the first word picks a mode: `mux d` the daemon,
`mux a` the agent surface, `mux web` the browser hub, no letter the
client. The wall lists DAEMONS: `$XDG_STATE_HOME/mux/hosts` names boxes,
tiles are each box's live sessions polled once a second, and the host
picker (`Ctrl-\ s`) births, forgets and adds without a key ever reaching
a session. `Ctrl-\ x` ends a session through the daemon, twice when
others hold it. A daemon lives until `mux d stop`; a read never starts
one, and the dial a user asked for runs `ssh HOST 'mux d endpoint
--start'` ONCE — the remote ensures and announces on the same stdout, so
a cold attach is one ssh run where it was three. The handoff's policy is
a step table in handoff.zig, and a warm miss on unchanged coordinates
pays one deadline (2.0 s, was 4.1 s). The browser hub reads the same
hosts file; the old wall file is retired. Daemon frames are nonblocking.

Not in this release: a v0.0.1-15 or older remote answers `mux d endpoint`
with usage and reads `[unreachable]` until it is upgraded by
`mux d stop` then `mux d start` — there is no in-place upgrade across
the rename.
