Problem or use case

I want to use opencode2 with t3code

Proposed solution

Add another provider for opencode2 in settings providers, will be easier to switch to opencode2 when it goes stable in a couple of weeks.

Why this matters

Users that have opencode2 can’t use t3 code.

Smallest useful scope

Add a toggle in current opencode providers for v1 /v2

Alternatives considered

I tried switching binary path to v2 but that didn’t work. I get the error:

OpenCode — Unavailable. Failed to execute OpenCode CLI health check: Unable to determine OpenCode version from 'opencode -
-version' output. T3 Code requires OpenCode v1.14.19 or newer.
