feat(brand): rename product to Recl∆Im (Reclaim) across app, bundle, docs

Recl∆Im — the F∆I product line for Pflicht-basierte
Wirkungsanalyse und Reform-Vorschlags-Pipelines. Replaces the
working title 'Law-Heatmap', which described the demo view
rather than the platform. Heatmap, Norms list, Hub view,
Methodik are now four panes of the same Recl∆Im app.

Renames in this commit:

  Flutter package      lawheatmap_app   -> reclaim_app
  macOS bundle id      ai.flemming.lawheatmapApp -> ai.flemming.reclaim
  macOS PRODUCT_NAME   lawheatmap_app   -> reclaim_app
  Theme tokens         LawHeatmapColors/Space/Radius/Typography/Theme
                       -> Reclaim*
  Surface card         LawHeatmapCard   -> ReclaimCard
  Top-level widget     LawHeatmapApp    -> ReclaimApp
  Theme files          lawheatmap_theme.dart/lawheatmap_tokens.dart
                       -> reclaim_theme.dart/reclaim_tokens.dart
  Widget file          lawheatmap_card.dart -> reclaim_card.dart
  Build script         build-macos.sh paths and headline string
  Docs                 MACHBARKEITSSTUDIE.md, METHODIK.md, RUN.md,
                       app/README.md, flow YAML
  UI strings           'F∆I Law-Heatmap' / 'Law-Heatmap'
                       -> 'Recl∆Im' / 'Recl∆Im (F∆I)' for vendor-
                       prefixed contexts

flutter analyze: clean. flutter test: 2/2 passing.

The local working directory stays fai_lawheatmap/ for now —
the dir is referenced by the .claude project metadata; renaming
it would break session continuity for no real gain. The Forgejo
repo was renamed via API in the same change-set (fai/lawheatmap
-> fai/reclaim), with the legacy slug serving a redirect
courtesy of Forgejo's built-in rename handling.
