Triage findings

The project uses pnpm as its package manager (there is a pnpm-lock.yaml that pins exact dependency versions). Running yarn dev instead bypasses that lockfile — yarn resolves its own dependency tree and can land on version combinations that are incompatible with each other.

The specific error ("Types of parameters 'target' and 'target' are incompatible. The types of 'state.selection.ranges' are incompatible") is a well-known CodeMirror 6 symptom when @codemirror/state and @codemirror/commands resolve to mismatched versions. With pnpm + the lockfile, @codemirror/state is pinned to 6.6.0 and @codemirror/commands to 6.10.3, which type-checks cleanly (pnpm tsc --noEmit on Linux produces only a deprecation notice, not this error).

Recommended fix:

# Install pnpm if you don't have it
npm install -g pnpm

# From the frontend/ directory
pnpm install
pnpm dev

If the error persists after switching to pnpm on Windows, please share the output of pnpm tsc --noEmit so we can check whether it's a genuine type incompatibility or a Windows-specific resolution issue.

Can you try using pnpm and let me know if that fixes it?
