Use the new snip run and check subcommands

[JoaoCostaIFG]

2 new subcommands were added to snip:

• run - safer way to specify the command to be run
• check - check if a command should be run with snip. For example, shell built-ins like cd and export would be rejected.

This PR:

• Replaces hardcoded unproxyable list with a runtime call to snip check
• Deduplicate findFirstPipe call - the AST was traversed twice
• Replace console.warn with client.log - per opencode recommendations (console.warn in plugin code mangles the UI)

Thanks for your contribution ! I’ve seen your contribution on snip repo, they haven’t been released yet. I’ll take a closer look at your PR when I have a little more time. At a quick glance, I think we’ll need to check the installed version of snip to prompt users to update it.

That's a good point, didn't think about that. I'll try to add a check for the snip version to preserve the previous behavior when using older version of snip (without the run/check sub-commands)

I don't think it's important to maintain backward compatibility. I'm more in favor of making sure that people using opencode-snip@latest are aware that they need to update snip.

Hey folks, any updates on this?

This PR has been superseded by PR #14 (#14), which builds on your foundational work adding snip check/`snip run` support and client.log replacement.

PR #14 additionally includes two critical fixes that were discovered while testing:

1. Multi-word snip check arguments: snip check -- "git log -10" returns no filter (one string arg). The command is now split into individual words: snip check -- git log -10 correctly returns filter: git-log.

2. All pipe segments are checked: Previously only the first command before | was evaluated. Now every pipe segment is independently resolved via snip check, with proper quote awareness and compound operator handling within each segment.

Thank you @JoaoCostaIFG for your contribution — the new PR includes full credit for your work in the Acknowledgements section.
