fix(assistant): lint, types and tests for the CI round

- agent loop and decisions without await in loops: steps as recursion,
  calls and applied changes in order through one promise chain, the
  independent reads and claims in parallel; part mapping in its own helpers
- place card, header and weather strip without refs or components created
  in render; long hooks and components split; state reset during render
- trip notes only in a turn's tool session, never an undo's; map view
  reported only while the assistant can run
- place strip scrolls through the strip's own smooth scroll, no physical side
- tests follow the raised limits and the new card fields; toasts read through
  a mocked useToast instead of a window global; baselines lowered where the
  counts fell
