Worker uses plain getopt_long(), not argp, so it has no free --version
handling like controller/scheduler. Adds a long-only OPT_VERSION=257
option and a handling case that computes xce_compose_version() into a
static buffer and returns before any startup work (check_user()/
xcecd_init/xcecd_start). Both startup INFO log branches (--peers and
no-peers) extended to log the identical buffer.
Live-verified: --version and both startup-log branches are
byte-identical (captured via a real daemon run under sudo).
Also updates bug-1519 (pre-existing, unrelated ASAN "Joining already
joined thread" abort during worker shutdown): independently reproduced
under real root during this task's review, refining its prior "never
reproduced under real root" note -- not a userns/unshare artifact, still
unfixed, does not affect this task's code path.
Task 3.3/13 of build-time-versioning. This closes out the "Core: C
daemon version display" phase (tasks 3.1-3.3).

repl_print_event_summary() (interactive REPL event echo) now prefixes
each echoed event with "[sim] t=<ns> (<human>) session=<N>", using the
same xce_core_now()/repl_format_ts_human()/session_count sources "info
session" already reports. Uses session_count+1, not the raw count:
events stream in and are echoed individually before the ReplaySession/
begin_round message that increments session_count is even read (file
order is event, event, ..., ReplaySession), so an echoed event always
belongs to the session about to begin.
Add sim_prescan_session_count() (sim.c): scans the replay file from the
current position via shape-only classification (mirroring sim_loop.c's
own ReplayEvent/ReplaySession/SnapshotEntry dispatch), counts
ReplaySession messages, then rewinds via fseek back to the exact ftell()
position -- same rewind technique sim_locate_and_load_snapshot() already
uses. Wired into sched_sim_driver_start(): prints "[sim] replay file
contains N sessions" once at load, non-fatal on scan failure.
Add test_replay_load_reports_total_session_count; extend
test_step_echoes_events_before_session_decisions with t=/session=1
assertions.

apply_committed_entry()'s shared WAL_JOB_START/FINISH/STOP/RESUME/RUSAGE/
CKPT/PREASON dispatch case only ever called the generic, state-only
apply_job_update_transition(j, state) -- start_time/finish_time/run_time
were never touched, so `xcecli joblist` always showed StartTime=0 for
RUN/DONE/EXIT jobs and FinishTime=0 for DONE jobs (EXIT jobs got a
finish_time only via the separate, richer WAL_JOB_FAIL dispatch path).
Fix is additive: stamp time(NULL) keyed on wal_type right after
apply_job_update_transition() succeeds, still under the same
lock(j, RTTI_LOCK_WRITE) -- WAL_JOB_START sets start_time, WAL_JOB_FINISH
sets finish_time and derives run_time. No change to
apply_job_update_transition()'s signature or the dispatch structure.
Add test_ace_job_start_sets_start_time and
test_ace_job_finish_sets_finish_time_and_run_time to
test_apply_committed_entry.c, following the existing tace_seed_job
fixture pattern.

makeGroup()'s existing-group update path (hit whenever a config-push
re-applies a group name that already has members, e.g. a retried config
push during controller failover) released xce_g_member_t.u.name via
FREEUP() (plain free()). u.name is allocated by makeString(), an
rtti-managed, refcounted pointer that is not a malloc()-base address --
freeing it directly corrupts the heap. group_killer() in the same file
already releases the identical field correctly via dereference().
Switch both FREEUP(m->u.name) call sites to dereference(m->u.name) to
match. Add a regression test that re-applies config for the same group
name twice, reproducing the exact ASAN bad-free at group.c:234 pre-fix.
This is the root cause of the reproducible xce_scheduler
"free(): invalid pointer" SIGABRT crashes seen during 3-attempt
controller-failover config-push retries (8 confirmed core dumps).

Covers the printf/tlog-prefix consistency fix, the "info resource all"
UX fix, and the resource-distribution-mapping roadmap gap surfaced while
investigating total/current display for GLOBAL/SHARED resources.
Covers the low-risk backlog cleanup pass (stale roadmap entries,
job_ctrl/OP_upgradeConfig investigations) plus one self-correction lesson
