fix: refresh magic notes after external updates

Subscribe the open Magic Notes workspace to committed database changes from desktop and Agent/MCP writes. Preserve selections and unsaved drafts during refresh and external deletion.

File-level commit includes existing runtime edits in shared files; their remaining dependencies are still in the working tree.

Release note: Magic Notes now updates automatically after Agent/MCP edits while preserving your selection and unsaved drafts.
