Previously the catch roll script wrote catch_pending=False to disk before
the Bash process exited. The PostToolUse hook fired after exit, saw False,
and could auto-resolve the encounter on the same run as the catch attempt.
Fix: the hook now owns the flag lifecycle.
- Hook clears catch_pending after consuming it (protects exactly one run)
- Roll script never touches catch_pending (no premature clear)
- On failure, flag stays True through the roll, cleared by hook afterward
- Next /buddymon catch call re-sets it at the top as before
Net effect: a failed catch attempt always gets one full clean Bash run of
grace before auto-resolve can fire again.
