Set Obsidian plugin to desktop-only to suppress mobile loading errors

[nathancashion]

Summary

• Sets isDesktopOnly: true in the Obsidian plugin manifest to prevent the plugin from loading on mobile devices
• The plugin currently relies on desktop-specific APIs (CodeMirror 6 editor extensions, tldraw canvas views, DOM event handlers for drag-and-drop) that cause errors when Obsidian attempts to load it on mobile
• This is intended as a stopgap — iPad support is plausible in the future since most of the plugin's core functionality (CM6 extensions, vault access, Supabase sync) can work on tablet, but a dedicated mobile compatibility effort would be needed for touch interactions and canvas features

Test plan

• Verify plugin loads normally on desktop Obsidian
• Verify plugin no longer appears / causes errors on Obsidian mobile

@nathancashion Thanks for this fix! isDesktopOnly: true is definitely the right call. One thing to flag: discourse-graph-obsidian is a publish mirror. When we cut a release, publish.ts pushes the source files from our monorepo, which would overwrite this change.

The fix needs to land in apps/obsidian/manifest.json in the main monorepo to persist. Would you be open to opening a PR there, or would it be easier if we apply it on your behalf and credit you?

@trangdoan982 Yeah, I discovered that this was a mirror while trying to vibecobe a fix on my local repo. I'm a novice with GitHub, so don't fully understand the difference, but I'll try to repost the PR there.
