Unexpected Execution Halt: No Hook Commands Processed

Bug Description
Claude Code just stops in the middle of what it was doing. I can see this in the debug logs.\
\
[DEBUG] Executing hooks for Stop
[DEBUG] Getting matching hook commands for Stop with query: undefined
[DEBUG] Found 0 hook matchers in settings
[DEBUG] No match query, returning all 0 hooks
[DEBUG] Found 0 hook commands to execute
[DEBUG] AutoUpdaterWrapper: Installation type: unknown, using native: false\
\
The end result is that CC stops in the middle of a task and doesn't execute anything.
