v0.5.0

- zt status: show live-negotiated protocol for auto tunnels (auto (http2)/auto (quic))
- --version flag (was silently broken — ldflags targeted a nonexistent symbol)
- zt <name> status/logs/restart/down now works same as zt status/logs/restart/down <name>
- richer root --help (surfaces --tcp, completion, name-first alias)
- README: documented shell completion, 502-despite-healthy-QUIC troubleshooting, no-self-update note
