The last two Publish runs (v3.0.0 in #21, v3.0.1 in #22) failed at the Marketplace publish step:
@types/vscode ^1.137.0 greater than engines.vscode ^1.85.0
The Chronicle 18 upgrade bumped the @types/vscode range to ^1.137.0 while engines.vscode stayed at ^1.85.0, and yarn resolves the caret range to 1.137.0 — so vsce's type/engine compatibility check fails.
This pins @types/vscode to exactly 1.85.0 so the locked type surface matches the declared engine baseline. Verified locally: yarn ci passes and vsce package --no-dependencies succeeds.
Fixes the publish failure; merging should cut a patch release and publish cleanly.
