roboomp 841d51aed0 fix(coding-agent): guarded nested task rendering cycles
- Added cycle and depth guards for nested task progress rendering so async fan-out snapshots cannot recurse until the TUI crashes.
- Shortened long Windows '/data/workspaces/can1357__oh-my-pi__2551/.omp-session/2026-06-14T07-09-37-753Z_019ec4f6-ee59-7000-8226-e1b7ed0680e9/local' roots into temp-backed session roots before plan/handoff writes hit MAX_PATH.

Fixes #2551
