feat: v1.1.0 release - session ID tracking, async hooks, new skills

- Add session ID to session filenames (Issue #62)
- Add getSessionIdShort() helper for unique per-session tracking
- Add async hooks documentation with example
- Create iterative-retrieval skill for progressive context refinement
- Add continuous-learning-v2 skill with instinct-based learning
- Add ecc.tools ecosystem section to README
- Update skills list in README

All 67 tests passing.

+#   start-observer.sh stop   # Stop running observer
+#   start-observer.sh status # Check if observer is running
