chore: upgrade Biome to v2.4.2 and add noRestrictedImports rule

Upgrade Biome from 1.9.4 to 2.4.2 to enable the noRestrictedImports
lint rule, which bans whole-library lodash imports (e.g.
`import { debounce } from "lodash"`) while allowing per-method deep
imports (e.g. `import debounce from "lodash/debounce"`).

New v2 rules that would flag pre-existing code are disabled to keep
this upgrade non-breaking. These can be enabled incrementally.
