This reverts commit 6e979d0.

Still too many intermittent failures due to timing changes.

---

Summary by cubic

Reverts the recent pattern selection changes and restores the previous active/default charm flow to reduce intermittent timing failures. Also stabilizes integration tests with simpler, more deterministic checks.

• Refactors

  • Restore unified pattern resolution in AppView via viewToPatterns and remove pattern caching/helpers from RuntimeInternals.
  • Rename built-in type from "space-root" to "space-default" and align PatternFactory/BodyView APIs; iframe test now reads _activePatterns.
  • Simplify CharmsController.create to return CharmController consistently.

• Bug Fixes

  • Replace fragile wait loops with direct queries and assert-based checks across integration tests; add small sleeps where needed.
  • Make ct-list and ct-tags edits/removals reliable by dispatching clicks and waiting for DOM changes.
  • Re-enable instantiate-recipe flow and assert navigation via URL change.
