chore(registry): trim the published archive to runtime files

The registry security scan flags a node version on ANY finding, even
severity "info", so every file in node.zip is scan surface. Dev-only
trees (tests/, docs/, scripts/, .agents/, Vue widget sources) accounted
for ~44 of the 115 findings that flagged 1.2.2-1.2.4.

comfy-cli builds the archive as `git ls-files` minus `.comfyignore`
matches, so this drops 501 of 1033 tracked files while keeping every
runtime path: py/, web/, static/, templates/, locales/,
example_workflows/, data/supporters.json, refs/, standalone.py.

Dropping vue-widgets/ is deliberate: the prebuilt bundle ships in
web/comfyui/vue-widgets/, and py/vue_widget_builder.py skips its mtime
check when src/ is absent, so end-user installs no longer risk an
npm install at startup.
