brooklyn! 75be8fb463 test(mcp): stamp breaker-open time on the monotonic clock, not a literal (#69003)
test_session_expired_retry_waits_for_new_session hardcoded
_server_breaker_opened_at["hindsight"] = 123.0 to simulate a circuit breaker
whose cooldown has already elapsed. But the breaker in tools/mcp_tool.py
compares that stamp against time.monotonic() (age = monotonic() - opened_at,
elapsed when age >= _CIRCUIT_BREAKER_COOLDOWN_SEC). time.monotonic()'s origin
is arbitrary and small on a freshly-booted CI container, so age worked out to
only a few seconds there (< the 60s cooldown) — the breaker stayed open, the
half-open probe never fired, and the retry returned the "unreachable" error
instead of "bank ok". It passed on long-uptime dev boxes (large monotonic)
and failed under CI, with the reported "Auto-retry available in ~Ns" drifting
run to run as the container's monotonic clock varied.

Stamp opened_at relative to the same clock the code reads
(time.monotonic() - _CIRCUIT_BREAKER_COOLDOWN_SEC - 1.0) so the cooldown is
provably elapsed regardless of the monotonic origin, exercising the intended
half-open transition deterministically.
