teernisse da327fe759 Rewrite TUI as full-screen Bubble Tea two-pane interactive browser ...

Replace the line-based stdin pagination loop with a charmbracelet/bubbletea
application providing a responsive two-pane layout: a filterable deal list
on the left and a scrollable detail viewport on the right.

Key capabilities:

- Async startup: spinner + skeleton while store/deals are fetched, then
  transition to the interactive view. Fatal load errors propagate cleanly.
- Grouped sections: deals are bucketed by category (BOGO first, then by
  count descending) with numbered section headers. Jump with [/] for
  prev/next and 1-9 for direct section access.
- Inline filter cycling: s (sort: relevance/savings/ending), g (bogo
  toggle), c (category cycle), a (department cycle), l (limit cycle),
  r (reset to CLI-start defaults). Filters rebuild the list while
  preserving cursor position via stable IDs.
- Fuzzy search: / activates bubbletea's built-in list filter. Section
  jumps are disabled while a fuzzy filter is active.
- Detail pane: full deal metadata with word-wrapped text, scrollable
  via j/k, u/d (half-page), b/f (full page). Tab switches focus.
- Terminal size awareness: minimum 92x24, graceful too-small message.
- JSON mode: tui --json fetches and filters without launching the
  interactive UI, consistent with other commands.

New files:
  cmd/tui_model.go      — Bubble Tea model, view, update, grouping logic
  cmd/tui_model_test.go — Tests for sort canonicalization, group ordering,
                           and category choice building

Dependencies added: charmbracelet/bubbles, charmbracelet/bubbletea.
Transitive deps upgraded: lipgloss, x/ansi, x/cellbuf, x/term, go-colorful,
