chore(deps): batch dependabot npm dependency bumps (#122)

Combine the open Dependabot npm/yarn update PRs into a single change so
they review, run CI, and land together:

* @biomejs/biome 2.4.16 -> 2.5.0 (#116); also bump the biome.json
  $schema URL to 2.5.0 to match the CLI.
* vitest -> ^4.1.9 across root, builder, cli and simulator (#117)
* turbo ^2.9.14 -> ^2.9.18 (#118)
* @types/node 25.9.1 -> 25.9.3 across root, builder, cli and simulator
  (#119)
* vite 8.0.14 -> 8.0.16, a transitive security-group bump (#120)

Supersedes #116, #117, #118, #119, #120.
