Why

Org admins can now set which reasoning controls a model accepts in the OpenCode Console (anomalyco/opencode-console#3690). The Console sends them as reasoning_options in the pulled config, but 1.x ignored that key in config, so the edits had no effect for 1.x users.

What changes

• Config: adds provider.*.models.*.reasoning_options, in the same format models.dev uses.
• Variants:
  • When reasoning_options is set, OpenCode builds the model's variants from it with ProviderTransform.reasoningVariants, the same path catalog models use. These replace the catalog variants.
  • An empty list means no variants.
  • Configured variants still merge on top.
• SDK: regenerated the SDK types.

Verification

• Typecheck passes for opencode and core.
• Added a provider test for replaced, overlaid, and empty reasoning options. Tests run in CI.

Closing: we're not targeting 1.x for Console reasoning edits. 1.x keeps building variants from its own models.dev data, and ignores the reasoning_options the Console sends.

Reopening: we do want 1.x to build variants from the reasoning options the Console sends.
