feat(jsx/dom): skip calculate children if props are the same

[usualoma]

Oops, the biggest point of React, the feature of not calculating the child element again if the properties are exactly the same, was not implemented. So it seems that https://github.com/orgs/honojs/discussions/3044 did not give the expected result.

If this pull request is merged, it would benefit from optimisation by React Compiler.

The author should do the following, if applicable

• Add tests
• Run tests
• bun run format:fix && bun run lint:fix to format the code
• Add TSDoc/JSDoc to document the code

@usualoma Thanks!

@sor4chi Can you review this?

Hi, @usualoma

Thanks for fixing it.
When I built the PR code in my environment and then set up the example ReactCompiler sample code as dev and accessed it, I encountered a mysterious behaviour where the text and handlers disappear after the DOM is rendered. Could you please try to reproduce this?

@sor4chi Thank you. Sorry for the hassle.

In my environment, it works as follows.

I've built and archived the hono from this pull request branch into a tgz archive and created a version to install from there, so can I ask you to try this again with the node_modules removed?

[sor4chi]

Sorry, I tried it in various ways, tgz, local link, etc, but it didn't work. Maybe it's my environment...
Can you try this? @yusukebe

@sor4chi @usualoma

It works well on my machine!

Thanks, the test looks fine and it seems to be completely my environment.
I have no problem proceeding as it is!

[yusukebe]

LGTM!

[yusukebe]

@sor4chi Okay! Thank you for reviewing.

@usualoma I'll merge this into the next and release the 4.5.0-rc.2 now. Thanks!
