Add Kiro subscription provider

[guillaumegay13]

Summary

• add Kiro as a subscription-only provider using local Kiro CLI OAuth instead of an API-key/token paste flow
• read and refresh the Kiro CLI OAuth token cache, store the encrypted CLI token blob, and unwrap it for proxy/model discovery
• dynamically discover Kiro models from the Kiro AWS endpoint and forward chat through a Kiro eventstream adapter
• add the Kiro provider UI, icon, CLI OAuth connect view, and focused backend/frontend coverage

Validation

• npm --workspace manifest-shared run build
• npm test --workspace=manifest-backend -- --runInBand routing/oauth/kiro-cli-token.spec.ts routing/oauth/kiro-oauth.service.spec.ts routing/kiro-oauth.controller.spec.ts routing/proxy/__tests__/proxy-fallback.service.spec.ts routing/proxy/__tests__/proxy.service.spec.ts routing/proxy/__tests__/provider-client.spec.ts routing/proxy/__tests__/provider-endpoints.spec.ts routing/proxy/__tests__/kiro-adapter.spec.ts model-discovery/model-discovery.service.spec.ts model-discovery/provider-model-fetcher.service.spec.ts common/constants/providers.spec.ts common/utils/provider-inference.spec.ts
• npm --workspace manifest-backend run build
• npm --workspace manifest-frontend run build
• npm test --workspace=manifest-frontend -- providers.test.ts ProviderIcon.test.tsx
• git diff --check HEAD

Notes: frontend build still reports the existing large Playground chunk warning. Backend Jest still prints the existing open-handle warning after passing.

Summary by cubic

Adds Kiro as a subscription-only provider using local Kiro CLI OAuth (cli_oauth). Discovers models from AWS and proxies chats to Kiro’s JSON event-stream with OpenAI-compatible SSE/JSON responses.

• New Features

  • CLI OAuth: read/refresh Kiro CLI token cache, store encrypted CLI blob, unwrap for discovery/proxy; POST /api/v1/oauth/kiro/cli-connect endpoint and a CLI OAuth connect UI with copyable kiro-cli login --use-device-flow command and Kiro icon.
  • Model discovery: call AmazonCodeWhispererService.ListAvailableModels with pagination, infer context windows, and register kiro/* models; provider inference updated.
  • Proxy: Kiro adapter converts OpenAI-style requests, targets AWS AmazonCodeWhispererStreamingService.GenerateAssistantResponse, parses JSON event-stream frames (incl. errors/reasoning), and streams SSE or returns JSON; provider endpoint set to https://q.us-east-1.amazonaws.com with x-amz-target.

• Migration

  • Install and log in with Kiro CLI: kiro-cli login --use-device-flow.
  • In Providers, select Kiro subscription and click Connect. Optionally set KIRO_CLI_BIN or KIRO_CLI_TOKEN_CACHE to customize CLI path/cache.
