Chinesezjc ff604dc876 fix(code-runtime-python): clear stale SIGKILL timer and clamp inherited soft rlimit ...

Two further review findings on the CPython backend:
- The grace-window SIGKILL timer was left armed after settlement, so on a
  normal completion a kill(-pid) could fire up to graceMs later and strike a
  recycled pgid once the kernel reused the leader's pid. settle() now clears
  the timer the moment the process group is confirmed empty (the normal path
  and when the poll sees the survivor gone), bounding the reuse window to the
  genuine-survivor case where the group cannot be empty to reuse.
- _clamped bounded rlimits by the inherited hard limit only, silently raising
  an inherited soft limit stricter than the request (loosening RLIMIT_AS or
  deferring RLIMIT_CPU SIGXCPU). It now clamps each side against its own
  inherited counterpart and pins soft under hard, keeping the strictest of
  configured and inherited. Adds an inherited-soft-limit regression test.

Agent Note expanded to seven fixes with the two new rejected alternatives;
zh pair re-recorded.
