release(v4.11.1): ship pre-built dist/ to npm registry

publish-all.ts now does a tsc → dist/ build per package before pack, then
rewrites package.json's main/types/exports to point at the built artefacts
and ensures `files: ["dist"]` so the tarball ships only the built code.
The in-repo package.json is restored in the finally block so dev/typecheck
keep working without a build pass.

Why: strict-mode consumers (Cyndr) were forced to recompile Shade source
under their own tsconfig and tripped on internal `process.env.X` accesses
and implicit-any parameters. Shipping pre-built `.js` + `.d.ts` makes the
strictness contract live entirely inside Shade.
