Restore the source package manifests

Commit cb6801a replaced packages/{dev,dev-test,dev-ts}/package.json with the
build's rewritten copies: exports pointing at ./index.d.ts, ./cjs/* and
other files that exist only under build/, and main/module/types to match.
In the workspace that made @pezkuwi/dev-test/globals.d.ts unresolvable, so
tsc failed on every describe/it/expect (build and test red since January),
and packages/dev lost its devDependencies.

The four fields are back to the source form (identical to upstream's),
packages/dev's devDependencies are restored with React aligned to dev-test's
19, dev-test's @types/jsdom returns, and the generated globals.d.cts that was
committed beside the sources is removed. packageInfo follows the version.
