Bug: `RangeError: Out of memory` crash after `git commit` fails due to renamed hook script

Title: Bug: RangeError: Out of memory crash after git commit fails due to renamed hook script

Body:

Description

When asking Claude Code to perform a git commit and push, the session crashed with a RangeError: Out of memory. This occurred after a session where I had used Claude to rename a configured hook script (activity_hook.sh -> activity_hook.sh.deprecated).

It appears that after the file was renamed, Claude's hook runner did not update its internal state and continued to attempt executing the hook from its old, now non-existent, path. This led to a "No such file or directory" error, followed by a long "Determining..." phase, and ultimately a fatal out-of-memory crash.

Steps to Reproduce

1. In a git repository, configure a hook in .claude/settings.json, for example, a PreToolUse hook pointing to .claude/hooks/activity_hook.sh.
2. Start an interactive claude session.
3. Use Claude to rename the hook script (e.g., mv .claude/hooks/activity_hook.sh .claude/hooks/activity_hook.sh.deprecated).
4. Ask Claude to perform an action that would trigger the now-moved hook, such as commit and push.
5. Observe the hook execution failure and subsequent crash.

Expected Behavior

Claude should recognize that the hook script at the configured path no longer exists. Ideally, it would fail gracefully, report that the hook is missing, and continue the session without crashing. It should not attempt to execute a script from a path it was responsible for moving within the same session.

Actual Behavior

1. Claude attempts to execute the hook from the original, now non-existent, path.
2. It logs a No such file or directory error for both PreToolUse and Stop hook events.
3. The agent gets stuck in a "Determining..." state for an extended period (75s+).
4. The entire process crashes with a RangeError: Out of memory.

Environment

• Claude Code Version: ~1.0.80
