Joseph Doherty a9ceba00d0 fix(communication): resolve Communication-001 — early stream termination handling ...

DebugStreamService.StartStreamAsync awaited the initial debug snapshot inside
a try whose only handler was catch (OperationCanceledException). When the
stream terminated before the snapshot arrived, onTerminatedWrapper completed
the await with an InvalidOperationException that escaped the catch — the
caller got a raw, untranslated exception and the service did no teardown of
its own on that path.

Replaced with catch (Exception): it removes the session entry, sends
StopDebugStream to the bridge actor via the local reference (deterministic
teardown, idempotent), and throws a descriptive exception — TimeoutException
for the 30s timeout, otherwise an InvalidOperationException naming the
instance/site and wrapping the cause.

Re-triaged Critical -> Medium: the originally-claimed multi-minute site-side
resource leak does not occur (the bridge actor self-terminates on every
onTerminated path). Adds the first DebugStreamService test, which fails
against the pre-fix code.
