feat: add Kiro provider for AWS kiro-cli usage tracking

Add support for tracking Kiro (AWS) usage via the kiro-cli tool.
Uses CLI PTY approach running `kiro-cli chat --no-interactive "/usage"`
to fetch monthly credits and bonus credits data.

- Add UsageProvider.kiro case and IconStyle.kiro
- Add KiroProviderDescriptor with CLI fetch strategy
- Add KiroStatusProbe for parsing ANSI-decorated CLI output
- Add KiroProviderImplementation (minimal, no custom login flow)
- Add ProviderIcon-kiro.svg (stylized K in AWS orange)
- Update widget views and provider registry
- Add docs/kiro.md and update README.md, docs/providers.md
- Gate Kiro usage on whoami login check
