feat(scheduler-sim-decision-trace): hook resource-requirement branching

Browse source 
Task 3.2: single requirements, top-level compounds, alternatives and
members push their path level and record one begin and one end; member
failures record the members not tried, merge failures and skipped
alternatives are separate entries, the chosen alternative or all-failed
is recorded, and each compound attempt's reasons are captured before the
job's stored reason is replaced. Scheduling results are unchanged.
