jackandClaude Fable 5 fa136d8973 Run perf benchmarks serially in their own CI step ...

The intermittent CI hang was caught by the new job timeout: the run
froze on the last remaining parallel test slot, an XCTest measure
benchmark (testNostrInboundEventHandling_freshEvents), after 4 hangs
in 5 runs - while the same suite completes in seconds locally and the
test itself is bounded. Independent of the micro-cause, benchmarks
do not belong inside the parallel suite: measuring while test processes
contend for cores is where our 2x CI variance came from. The parallel
run now skips benchmarks (BITCHAT_SKIP_PERF_BASELINES=1) and a
dedicated serial step runs them on an otherwise idle runner with a
6-minute step timeout, feeding the floor gate as before.
