🔍 feat(bdd): add state tracer and fix config reload timing

- Add STATE_TRACER_README.md with full documentation
- Add state_tracer.go for per-process BDD execution tracing to $TMPDIR
- Integrate tracing hooks in suite.go (SCENARIO_START/END, JWT_RESET, DB_CLEANUP)
- Fix config_steps.go: increase file recreation delay to 1100ms for 1s polling interval
- Fix config_test.go: update expected values to match current implementation
- Document findings: sequential per-feature execution, shared DB, in-memory JWT secrets
- Identify root causes of intermittent failures
