fix(ui): external adapter selection, config field placement, and transcript parser freshness

- Fix external adapters (hermes, droid) not auto-selected when
  navigating with ?adapterType= param — was using a stale
  module-level Set built before async adapter registration
- Move SchemaConfigFields to render after thinking effort (same
  visual area as Claude's chrome toggle) instead of bottom of
  config section
- Extract SelectField into its own component to fix React hooks
  order violation when schema fields change between renders
- Add onAdapterChange() subscription in registry.ts so
  registerUIAdapter() notifies components when dynamic parsers
  load, fixing stale parser for old runs
- Add parserTick to both RunTranscriptView and
  useLiveRunTranscripts to force recomputation on parser change
