Nimbalyst v0.56.6

We've just shipped Nimbalyst v0.56.6 with support for Opus/Sonnet 1M, /skills showing up in the list, mobile app keep awake, plan fixes, and  performance/reliability.

Improvements

• We now support Opus/Sonnet 1M
• Many of the mobile app issues were because people's desktop was going to sleep. You can now set a mobile app keep awake in the settings that will enable synch to continue
• Plan mode had some problems. Its been re-implemented to just use what Claude Code and Codes do through the SDK.
• Slash command typeahead now shows all skills (user, plugin, and extension) after first response. [Think we fixe this this time]
• Force-paste plain text without attachment conversion with Cmd+Shift+V
• Hide or show navigation gutter buttons via context menu
• PromptQuickOpen scrolls the transcript to the selected prompt

Fixes

• Improved handling of large projects, reducing pauses
• MCP connections stay alive during long tool waits via SSE keepalive pings
• AI sessions with pending questions now resume correctly after app restart
• Sessions no longer get stuck as "running" after a git commit proposal
• AskUserQuestion no longer hangs when routed through the MCP server path
• Duplicate last message no longer appears when loading a session transcript
• Queued prompts now continue correctly after guarded turn completion
• File tree loading spinner no longer spins forever on empty workspaces
