Code editor, full PR control & four languages

• Code editor: edit files right in the app — with syntax highlighting, auto-indentation and direct commit. Creating and deleting files included
• Full pull request control: change base branch, milestone and reviewers, attach comments to individual diff lines, update the branch with a tap — with a prominent mergeable status
• Comments, all around: edit, delete, add emoji reactions, and follow an issue’s complete activity timeline
• Manage releases: edit and delete releases, upload or remove file assets
• Attachments now show in list overviews, not just in detail
• Spanish and French localization — gyokuro now speaks four languages
• Long lists load completely — nothing is silently truncated anymore
• Clearer error messages, lower memory use and clean teardown of network connections when switching accounts
