remove the map and ui shim packages

Both failed the deletion test in the telling direction:

- @trails-cool/ui: Button/Input/Card had zero consumers — both apps
  roll their own elements inline. The only live part was a 6-line
  styles.css (the Tailwind entry + one keyframe), which now lives in
  each app as app/styles.css.
- @trails-cool/map: MapView and RouteLayer had zero consumers; the
  package was otherwise a re-export of two map-core constants, and the
  two import sites now use @trails-cool/map-core directly. The
  "map components go in @trails-cool/map" convention had drifted long
  ago — the real map components live in apps/planner/app/components.

CLAUDE.md's repository structure and conventions updated to match
reality (including pointing shared-type guidance at the post-#515
sources: db row types, api contracts, Waypoint in types). Dockerfiles
no longer COPY the deleted package manifests.
