Renn F 21007e122f fix(mcp): do_server per-verb circuit breaker mirrors flow_server ...

Smoke-6 surfaced the gap. main-pm called note(scope='decision') with
context: null 8 times in a row — every one returned incomplete_input
and the agent kept retrying. The flow_server had a breaker (C1) but
do_server didn't, so content-tool rejections went uncapped.

Mirror the flow_server pattern:
- _CIRCUIT_REJECTION_KINDS = {tracing_gap, invalid_state,
  not_authorized, incomplete_input} (same set)
- _record_and_check_circuit posts to the SDK's /verb/attempted on each
  counted rejection
- When the SDK reports open=true, the original rejection envelope is
  REPLACED with the circuit_open envelope so the agent stops retrying

The SDK side (agent_sdk/server.py) already accepts arbitrary verb
names; no changes there. note hits the default cap of 3 retries / 60s
from foundation.agent_loop. After the third incomplete_input the
agent gets circuit_open and the loop ends.

9 new tests pinning the contract.
