Release v0.2.12

• Web: Separated server row actions in the server picker so hint navigation and row interactions behave more predictably. (@isomoes)
• UI: Removed the desktop sidebar toggle to simplify the main web layout and reduce redundant navigation controls. (@isomoes)
• Home: Skipped project bootstrap work on the home screen so the landing view loads with less unnecessary session setup. (@isomoes)
• Branding: Updated iKanban naming and copy across the web UI to keep product text consistent. (@isomoes)
• Docs: Refreshed the README Bilibili video link. (@isomoes)
