[Feature]: Integration with Rsdoctor

[fi3ework]

What problem does this feature solve?

Some rough ideas about the features we could provide:

• Inspect the bundled size locally (only bundled files of user's package)
• Inspect the size will be bundled into the application (include package's dependencies, similar to https://pkg-size.dev/ and https://bundlephobia.com/)
• GitHub Action to measure the diff of the metrics.

What does the proposed API look like?
