Use RLock instead of Lock for _close_lock so close() can call
_shutdown() without deadlocking — previously the session never
marked itself closed, causing infinite keepalive sends.
Mask kit checksums to unsigned 32-bit for hex display so negative
i4 values render as proper 8-digit hex (e.g. d3984c51 not -2c67b3af).
Tested against live device at 192.168.1.251 — full handshake,
schema read, and component tree load confirmed working.

New checkbox in Preferences (default off). When enabled, every DASP
send (>>>) and receive (<<<) prints message type, seq/ack numbers,
payload size, and remote address to stdout.

Port the DASP transport and Sox protocol stack from sedonaOntrol Java
to Python, enabling live device editing alongside the existing offline
SAX editor. Lazy-loads components on navigation, caches them, and
subscribes to COV events for the active wiresheet.
New files: dasp.py, sox.py, device_session.py, connect_dialog.py,
live_hooks.py. Modified: app_state.py (live-mode state), main.py
(Device menu, COV polling, lazy tree expand), properties.py (Sox
write-through), sax_file.py (structural mutations route through
live_hooks), schema.py (find_manifest helper).
