feat(scheduler-sim-repl-verbosity): task 4.1 - RED-phase sim_print_decision Gate tests

Adds 3 tests in a new test_sim_print_decision_gate.c covering the old
unconditional per-decision echo (sim_loop.c's sim_print_decision())
no longer duplicating the Round Rollup's per-round summary under
`continue` mode (Requirement 2.3), while `step` mode and headless
(non-interactive) batch runs stay completely unaffected (Requirements
5.1, 5.4). This is exactly the duplication bug-1610 reported.

1 of 3 tests fails as expected RED evidence (continue-mode bare
"[sim] PEND jobid=..." line still appears alongside the Round Rollup's
own summary today); the other 2 (step-mode and headless regression
checks) correctly pass since they pin already-correct, unaffected
behavior.

New file rather than extending either sibling: test_repl_round_rollup.c
is already 1022 lines (222 over the 800-line cap), and
test_repl_event_echo.c (704 lines) deliberately keeps its fixtures
job-free (bug-1595 discipline), which this task's decision-producing
fixtures cannot follow.

No production code touched (sim_loop.c/repl.c/repl_rollup.c/repl_break.c
untouched) - tests only, per this task's RED-phase boundary. The actual
gate implementation is task 4.2.

- Cover: during continuous execution, no bare per-decision line appears outside the round summary; while single-stepping, full per-decision detail still prints exactly as before; a non-interactive (headless) replay's decision output is unaffected
- Observable: the new test cases fail while the old unconditional per-decision print path still runs alongside the new round summary
