deprecate jsr

[ryoppippi]

I first thought JSR is the future of package management.
If you build small library, JSR is fine.
However, if you make a kind of special library like bundler plugin, JSR is not a good option.

• They change dynamic import path
• They doesn't support peerDependency

So, for the next major version:

• I deprecate the jsr version
• I setup my own build environment, probably using bun-build or rolldown
• I remove jsr-related-packages like pkg-to-jsr
