* docs(#4570): add changelog fragment

* fix(#4570): preserve default-on watchdog fallback
* docs(#4570): qualify the chunked-mode orchestrator rules with the toggle
The two chunked-planning-mode stall-watch imperatives read as
unconditional, with the opt-out stated only in a following bullet. State
the PLANNER_STALL_DETECTION_ENABLED condition inline, matching the three
sites already qualified in plan-phase.md.
* chore(#4570): refresh compact-content baselines against rebased next
* fix(#4570): sync planner stall launcher
Keep the stall-detection helper aligned with the canonical runtime launcher.
