Plugins run server-side during the Quartz build step, not in the
browser. Setting platform: 'node' tells esbuild to treat Node builtins
as available externals and avoids CJS-in-ESM require() failures for
any bundled dependencies that use Node APIs.
Install github-slugger and hast-util-to-jsx-runtime as devDependencies.
These are peer dependencies of @quartz-community/utils that must be present
for tsup's DTS build to resolve all transitive type imports.
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.
