* test: use `import type` in more places
Several tests are failing because a module isn't being mocked. This is
due to the mocked module being imported before the mock being set up.
Switching to `import type` should elide the import fully.
* build: replace ts-jest with simple transformer
* chore: remove `ts-jest`
* chore: remove babel dependencies from root project
* ci: use Node.js 22.13.0 (instead of 22.12.0)
Node.js 22.13.0 introduces the `stripTypeScriptTypes` function
* fix: copilot feedback
* auto-install-peers=true
* save-workspace-protocol=rolling
* publishConfig.linkDirectory true by default
* resolve-peers-from-workspace-root is true by default
* set dedupeDirectDeps to true by default in @pnpm/core.
