Summary by cubic

Upgrade dev dependency jsdom from 29.1.1 to 30.0.0 to get new CSS APIs and fixes. This major bump raises the Node.js requirement and may affect style-related tests.

• Migration
  • Ensure test/CI environments use Node.js ^22.22.2, ^24.15.0, or >=26.
  • Update tests or snapshots if they rely on getComputedStyle() units (lengths now return pixels).
  • If using the canvas peer, ensure it satisfies canvas@^3.2.3.

^{Written for commit 1e7392f. Summary will update on new commits.}
