beforeShellExecution in hooks.json required a JSON response we never
provided, likely causing Cursor to silently break the entire hook
pipeline. Commenting out those entries (and afterShellExecution) from
HOOKS_CONFIG restores reliable preToolUse/postToolUse delivery. All
Python handler code is retained as dead code for reference.
Also reverts the is_cursor_frontmost() gate in _check_pending — pulses
should fire unconditionally when the approval delay expires.
