fix(scheduler): clock/resval/jobid-format fixes plus REPL live-operator gaps (task 12.5)

Bugs fixed, discovered across a day of live-operator testing against a
real deployed cluster:

- bug-1584: clock anchors never initialized to real wall-clock values,
  timestamps showed system uptime instead of Unix epoch.
- bug-1585: heap-use-after-free in the normal-mode driver's periodic
  resval update path -- core_events.c's RESVALS_FULL/_DELTA handlers do a
  shallow zarray_put() of the wire-decoded xce_val_t*, but driver.c's
  release_translated_payload() unconditionally freed the same decoded
  array right after, so the next periodic report for the same
  worker+resource triggered a UAF read via kill_sched_resval(). New
  regression test: test_resval_ownership.c.
- bug-1587/1588/1591: raw-ns/raw-uint64 jobid/timestamp prints across the
  REPL/SIM family converted to the same human-readable formatting already
  used elsewhere (fmt_jobid(), timestamp formatting).
- bug-1590: repl_info.c's XCE_VAL_NUMERIC checks corrected to
  Value_u_fvalue, fixing `info worker`/`info resource` falling back to
  0.00 for real numeric resvals.

task 12.5 (Req 5.22 amendment) -- five REPL gaps surfaced by a live
operator session, each with its own bug id:
- bug-1594: `continue`/`step` reaching EOF with no breakpoint hit now
  re-enters the REPL via xce_repl_on_replay_complete() instead of exiting
  the process; step/continue issued after replay is already complete
  re-prompt instead of silently exiting.
- bug-1595: `step`/`continue` now echo each input event (not just
  decisions) via repl_print_event_summary(), in real event/decision
  order.
- bug-1593: `info resource <name>|all` now reports resource definition
  metadata restricted to XCE_RESF_GLOBAL/XCE_RESF_SHARED resources, read
  from core->sharedInst, instead of aggregating host-based resources
  across every worker.
- bug-1596: repl_split_tokens() strips one matching pair of surrounding
  quote characters from each token.

See requirements.md's Req 5 AC 22 "Amendment (2026-08-19)" for the full
rationale on each of the five task 12.5 gaps.

Full scheduler suite green (41/42; the one remaining failure,
test_recordstart_symlink_escape_replies_error, is the pre-existing
unrelated bug-1560).
