fix: address remaining 3 Copilot review observations (round 3)

- teardown docstring: clarify marker removal is conditional (if empty)
- test_pre_existing_skills_not_removed: now actually calls teardown()
  to verify foreign skills survive uninstall (was only running setup)
- integration_switch Phase 1: replaced old_manifest.uninstall() +
  remove_context_section() with current_integration.teardown(),
  matching the pattern already used in integration_uninstall.
  This ensures custom teardown logic (e.g. Hermes global skills
  cleanup) runs during switches.
