Support OpenCode

[eucariop]

I have recently been using the OpenCode. Ideally, this tool would also integrate with it, as I find it to be comparable to Claude Code.

Yes, That would be great!

Amen. Also love the lack of provider lock-in OpenCode would give (from the CLI-tool angle).

Hey @localden!

Thanks so much for all the hard work on this! I'm optimistic about the future of Spec Kit!

I think OpenCode is doing a great job and we're so pumped to see PR #64 open. (thanks @aemr3!)

If you need any help getting this merged to main, we'd be happy to contribute. 💯

You guys are awesome. 😎

Thank you!
