perf(deps): share dependencies across checkouts via the bun global store

The isolated linker was already in use, but without the global store each
checkout copied a full dependency tree into its own node_modules/.bun.
Anyone keeping several worktrees open paid roughly 2G per checkout for
identical packages.

Enabling globalStore installs each package once into a shared store and
symlinks it in. Measured across a whole checkout: 2098M drops to 32M.

The store resolves dependencies through symlinks whose real path lies
outside the project, and TypeScript follows symlinks by default. A
dependency re-exporting React's own types, such as LucideProps extending
SVGProps<SVGSVGElement>, can no longer reach @types/react by walking up
from the store path, so its React-contributed props disappear. Pinning
the react and react-dom specifiers to the workspace copy fixes it for the
whole program, including inside dependency .d.ts files.

claw-app had no paths block of its own and inherited one through extends.
Since a paths block replaces rather than merges, the generated wxt
aliases are restated there alongside the redirect.

Verified by full typecheck in three configurations, all producing an
identical 39 findings:

  no store, no paths   (before this change)
  store + paths        (local development)
  paths only, no store (CI on the pinned bun, which ignores globalStore)
