DS4Server implementation plan

Only unfinished implementation work belongs here. DwarfStar remains the behavioral oracle for model execution, token processing, context accounting, KV-cache behavior, the HTTP API, and the built-in agent loop.

1. Finish native project and chat controls

• Add functional File, View, and Help menus; update native menu enabled state from the focused control; complete undo/redo behavior; and make transcript text selectable and copyable.
• File menu has an "export" menu to save a chat as markdown
• File menu has a new "menu" that opens a new chat in the currently active project. if the app is not on a project or session of a project in the sidebar, "new" is disabled
• View menu gets the "manage models" menu item, remove it from Window menu
• View menu gets toggle menu for sidebar with hotkey cmd-B
• Explain model/checkpoint mismatches where a session must rebuild context instead of resuming its existing checkpoint.
• the hellp menu must open a window with an actual documentation in it, that still needs to be constructed from the information and implementation

2. Add Dev Brain support

• Let the user select one Obsidian vault and give the local agent bounded Markdown memory_search, memory_read, memory_create, and memory_append operations outside project folders.
• the dev brain uses simple markdown lines to separate multiple memories
• check LLM wiki ideas online to see how obdsidian should be used by the LLM as a memory storage
• dev brain can be enabled/disabled in preferences to reduce system prompt
