Stop hook fires after every response, SessionEnd fires only when
session actually terminates. This was causing session-end.sh and
evaluate-session.sh to run on every response instead of at session end.
Fixes issue reported by user about hooks triggering every response.
Relative paths like ./hooks/... fail when the plugin is installed
because hooks run in the project directory, not the plugin directory.
Using ${CLAUDE_PLUGIN_ROOT} ensures scripts are found regardless of
where the plugin is installed.
Fixed paths:
- hooks/strategic-compact/suggest-compact.sh
- hooks/memory-persistence/pre-compact.sh
- hooks/memory-persistence/session-start.sh
- hooks/memory-persistence/session-end.sh
- skills/continuous-learning/evaluate-session.sh
