What

• AppStream summary: "Program vintage consoles" (German: "Retrospiele programmieren"), per Flathub quality rule (10-25 chars, no article, no full stop). Also changed in the desktop entry and the About dialog; all 16 catalogues carry a short translation (Tamil falls back to English).
• App name no longer translated in any catalogue (kept "Learn 6502 Assembly"), so the over-long translated names are gone. Android app_name and strings.xml/i18n regenerated to match.
• Homepage -> https://jumplink.eu/Learn6502/ (package.json homepageUrl and metainfo template).
• build-aux/check-about-metadata.js probes the name lookup with a synthetic metainfo, since the real one no longer has translated names.

Lint (gjsify flatpak check, quality, generated metainfo)

• Before: 13 errors, 35 warnings
• After: 0 errors, 15 warnings
• Remaining: name-long (19 chars, app name kept) and 14x release-notes-long (historic releases). Not trivial to fix without rewriting past release notes.

Validation

gjsify run check, check:format, check:versions, check:about, check:flatpak:sources, translations check green; lint reports only warnings that already exist on main. Commit hooks ran (no skips).
