feat: Add Kiro provider for AWS Bedrock Claude models

[ikeda-tomoya-swx]

Summary

Add support for Kiro (AWS CodeWhisperer) as a new provider, enabling access to Claude models via AWS Bedrock using Kiro CLI authentication.

Motivation

Kiro CLI provides a convenient way to access Claude models through AWS Bedrock without requiring direct AWS credentials configuration. This provider would allow opencode users who have Kiro CLI installed to use Claude models seamlessly.

Proposed Solution

• Add a new provider kiro with full LanguageModelV2 SDK implementation
• Use plugin-based authentication that reads tokens from Kiro CLI's SQLite database
• Support streaming responses via AWS Event Stream parsing
• Include support for extended thinking mode

Models to Support

• claude-sonnet-4-5
• claude-opus-4-5
• claude-sonnet-4
• claude-haiku-4-5
• claude-3-7-sonnet

Additional Context

Kiro CLI stores OAuth tokens in ~/.local/share/kiro-cli/data.sqlite3 (Linux/macOS) or %APPDATA%/kiro-cli/data.sqlite3 (Windows).

I believe this doesn't support the enterprise kiro plans?

I've got a kiro pro subscription, I think the plugin doesn't work with the paid plans?

---

Mainly want to do that so that I can leverage opus instead of sonnet, tried changing the configs and mappings but can't get past this yet:

Error: Unsupported model: claude-opus-4-5. Supported models: claude-haiku-4-5, claude-sonnet-4-5, claude-sonnet-4-5-thinking, claude-sonnet-4-5-20250929, claude-sonnet-4-20250514, claude-3-7-sonnet-20250219

Ended up forking the repo and piggy-backing on the kiro-ide tokens for now

Thank you for sharing the plugin. As you mentioned, it does seem that Opus is not supported at the moment. I understand the current limitation, but I would also like to be able to use Opus.

@thdxr
This implementation is based on authentication via the Kiro client (Kiro CLI), where OAuth tokens are stored in a local SQLite database. With this approach, supporting the use of Opus is possible.
Would you be willing to reconsider merging this implementation?

Hello @fpopa whats your current setup for kiro in opencode if you're still using it. I would like to set mine up too.
