Hook Execution Failure When Multiple Hook Types Combined

Bug Description
Summary of Findings:

The issue occurs when multiple hook
types are combined, not with
individual hooks:

• ✅ PreToolUse hooks alone: ESC works
• ✅ PostToolUse hooks alone: ESC

works

• ✅ Notification hooks alone: ESC

works

• ❌ All hooks combined: ESC fails

with "PostToolUse:Read hook execution
cancelled"

The bug is in Claude Code's hook
handling when a command is cancelled -
it tries to process PostToolUse hooks
for a cancelled operation but the
expected data structure is missing.
