chore(scheduler-allocator-runner): implementation complete; log bug-1897

Feature validation GO (ASAN scheduler suite 96/96, smoke replay clean on
the allocation path). Roadmap entry marked implemented with follow-ups.

bug-1897 (found by the validation smoke run, not caused by this feature):
xce_scheduler --sim segfaults in limit_job_election on a job whose
snapshot resreq failed to parse (pre-bug-1888-fix replays).
