Adds DispatchDecision (wraps JobAlloc), PendDecision (wraps
JobPendReason), PreemptVictim, PreemptDecision to controller.capnp.
Replaces task 7.1's empty SnapshotData placeholder wholesale with the
real 11-field struct (config/jobs/queues/workers/resources/resvals/
users/projects/prngSeed/internalState/internalVersion), in both the
capnp schema and its typemap.h C mirror. Extends ReplayDecision's
ts-only placeholder with a purely additive body union (dispatch@1/
pend@2/preempt@3).
Deviates from design.md's literal SchedUser/SchedProject mapnames
(xce_sched_user_t/xce_sched_project_t): those names are already real
C structs in sched/types.h, which shares a translation unit with
typemap.h in core_events.c/schedobj.c -- reusing them would be a
genuine duplicate-typedef compile error, not a style choice. Used
fresh mapnames (sched_snapshot_user_t/sched_snapshot_project_t)
instead, field lists unchanged, documented in both files.
Found and fixed a real bug mid-implementation: a doc comment's
literal */ substring prematurely closed a C block comment, corrupting
sched_snapshot_data_t and cascading into ~20 unrelated-looking compile
errors (bug-1493).
Five deep round-trip tests added to test_e2e_capnp.c. Full project
build and controller_unit_test (1082/1082) verified clean, confirmed
independently three times.
