Return the active tunnel for the same host:port:protocol instead of
starting a second Holesail instance; coalesce concurrent creates.
UI disables the create button and shows “already exists” feedback.

Batch typing into short frames, send UTF-8 instead of base64 for text,
exempt stream methods from the general rate limit, and skip heavy
middleware on terminalInput/resize for lower latency.
Production-grade xterm FitAddon resize, binary-safe I/O, TTY-safe
server streams, demuxed log viewer with line buffering, and auto-dismiss
deploy job panel without the full-screen spinner.
