feat: add Kiro provider with 12 models

[NachoFLizaur]

What does this PR do?

Adds Kiro (AWS CodeWhisperer) as a new provider with 12 models fetched from the ListAvailableModels API.

Models:

• auto (task-optimized routing, 1M context)
• claude-opus-4.7, claude-opus-4.6, claude-sonnet-4.6 (1M context)
• claude-opus-4.5, claude-sonnet-4.5, claude-sonnet-4, claude-haiku-4.5 (200K context)
• deepseek-3.2 (164K), minimax-m2.1 (196K), minimax-m2.5 (196K), qwen3-coder-next (256K)

Schema updated to allow kiro-acp-ai-provider as an npm provider (compliant with Kiro T&C).

Cost is 0 for all models (subscription-based, same as GitHub Copilot). Reasoning disabled on models as it's not supported by Kiro ACP

How did you verify?

• Model IDs, context limits, and output limits verified against the live ListAvailableModels API response
• Running Opencode with the updated model list after a Models.dev built using OPENCODE_MODELS_PATH showed the correct models and worked when interacting with them.

I've updated the schema to reference kiro-acp-ai-provider instead of kiro-ai-provider following the Kiro T&C update (see the opencode PR for more info). The new package uses Kiro ACP (via kiro-cli) instead of hitting the API directly, so it's compliant with the new terms.

Kiro ACP doesn't support Thinking capabilities like other providers, so it has been disabled for the models.

Added Opus 4.7 (thanks @hanool!).
