Subject: [PATCH] Mirror pyscript-template's app from its root

The template moved its app from pwa/ to the repo root, so sync_assets skipped the mirror and the portal's copy froze. It now copies the root's app files, workers/ and the vendored PyScript, replacing the mirror whole so dropped files leave too. Without a vendored interpreter it leaves the mirror alone.

Fixes #83.
