* feat(continuous-learning-v2): add lazy-start observer logic
Auto-starts observer when observer.enabled: true in config and no .observer.pid exists.

* fix(continuous-learning-v2): address PR review concerns
- Use flock for atomic check-then-act to prevent race conditions
- Check both project-scoped AND global PID files before starting
- Support CLV2_CONFIG override for config file path
- Check disabled file in lazy-start logic
- Use double-check pattern after acquiring lock

* fix(observe.sh): address PR review comments
- Add stale PID cleanup via _CHECK_OBSERVER_RUNNING function
- Add macOS fallback using lockfile when flock unavailable
- Fix CLV2_CONFIG override: use EFFECTIVE_CONFIG for both check and read
- Use proper Python context manager (with open() as f)
- Deduplicate signaled PIDs to avoid duplicate USR1 signals

* fix(observe.sh): wrap macOS lockfile fallback in subshell with trap
- Wrap lockfile block in subshell so exit 0 only terminates that block
- Add trap for EXIT to clean up lock file on script interruption
- Add -l 30 (30 second expiry) to prevent permanent lock file stuck

* fix(observe.sh): address remaining PR review comments
- Validate PID is a positive integer before kill calls to prevent
signaling invalid targets (e.g. -1 could signal all processes)
- Pass config path via env var instead of interpolating shell variable
into Python -c string to prevent injection/breakage on special paths
- Check CLV2_CONFIG-derived directory for disabled file so disable
guard respects the same config source as lazy-start
