v0.4.1 — New look

Changed

• New look: colour tokens from Radix Colors (MIT), Tabler icons (MIT), ring gauges
  for "how likely needed" (estimates marked with ~ and a dashed track), product
  avatars by category, bottom navigation on phones, deal cards with the usual price
  struck through, and tappable assistant suggestions built from your own products.
• Punchier copy in English and German: shorter, active, benefit-first. Tabs are
  now Now, List, Pantry and History. Estimates are still clearly marked as guesses.

Fixed

• Taps on icons now reach their buttons (SVG pointer-events).

Docs

• docs/MARKET.md: competitor analysis with a feature matrix and ranked parity gaps
  (#43–#49).
