fix: preserve command effect certainty across retries

Browse Source 
Separate per-attempt physical state from the logical execution history. The
executor now keeps one monotonic certainty accumulator joined through
joinMutationEffectCertainty, records MAYBE_APPLIED at dispatch, and reads the
accumulator from every retry-loop fence, final-invariant, cancellation and
timeout return.

A retry-time scope fence landing between the loop-entry check and the
pre-dispatch invariant can no longer downgrade an already dispatched command to
NOT_STARTED.
