Burke Autrey ff56251555 fix(streaming): Bedrock liveness watchdog (into #58962 breaker) + finite local timeout
Re-applied against v0.18.2. Upstream now covers the OpenAI-path stall watchdog
(cross-turn give-up breaker #58962) and the tool-batch deadline, so those are
dropped. Two gaps remain:

- Bedrock streaming had NO liveness watchdog and was excluded from the #58962
  breaker (it returns before _check_stale_giveup). Add an on_event hook to
  stream_converse_with_callbacks (fires per yielded event = true wire-level
  liveness), drive a stale timer from it, and wire Bedrock INTO the existing
  breaker: entry _check_stale_giveup, _bump_stale_streak on stall, raise to end
  the call (invalidate_runtime_client can't abort the in-flight botocore stream,
  so the streak escalates across turns like the OpenAI path), and reset the
  streak on success.
- local providers still got float('inf') stale timeout (watchdog disabled) — give
  a finite ceiling (HERMES_LOCAL_STREAM_STALE_TIMEOUT, default 900s).
- tests: on_event per-event + swallow; Bedrock stall bumps streak + aborts;
  pre-elevated streak aborts at entry; success resets streak.
