Subject: [PATCH] fix(deps): require use-sync-external-store ^1.5.0 so the ESM
 build loads in Node

dist/index.js imports `use-sync-external-store/shim`, which is kept
external. Before 1.5.0 the package had no `exports` map, so Node's ESM
resolver treats `/shim` as a directory and throws
ERR_UNSUPPORTED_DIR_IMPORT. That breaks anything that loads the ESM build
without a bundler: Vitest tests in apps that use reactfire, SSR that keeps
dependencies external, and plain Node scripts. The CJS build is fine.

Raise the floor to ^1.5.0 (lockfile: 1.2.0 -> 1.7.0).
