fix: @zenuml/core peer dependency is bundled into published package (9.3 MB)

[MrCoder]

Problem

@zenuml/core is declared as a peer dependency in package.json, but its dist files are being included in the published npm tarball:

• cloud-icons-eHuugVSv.js (~1.6 MB)
• zenuml.esm.js (~2.3 MB)
• sourcemaps

These appear under dist/node_modules/.pnpm/@zenuml_core@3.46.8/... in the published package, inflating it from ~100 KB to 9.3 MB unpacked (2.1 MB compressed).

Expected behavior

Peer dependencies should not be bundled into the package output. Consumers are expected to provide @zenuml/core themselves.

Impact

• Unnecessarily large npm package size
• Duplicate @zenuml/core code in consumer bundles
• Slower install times for downstream users

Likely cause

The Vite build config may be missing an external declaration for @zenuml/core, or the package's files field in package.json is too broad and includes node_modules artifacts.
