Move non-allowlisted packages from dependencies/peerDependencies to
devDependencies so tsup bundles them into dist/ instead of leaving
them as external imports that may not resolve at runtime.
Peer dependencies needed at build time for TypeScript declaration file
generation were missing from devDependencies. Without them, the DTS build
fails silently, producing no index.d.ts.
Pre-built output is now committed to the repository so that
Quartz can skip the build step during plugin installation.
The prepare script is removed to prevent redundant builds
when installing from npm/git.
tsup and typescript are only needed at build time — move to devDependencies
so they can be pruned after build. Dependencies already available from the
host Quartz installation are moved to peerDependencies to avoid duplication.
