Introspect Subagent and Global Hooks

This release brings two new capabilities to CLI 3.0 (early access) a built-in subagent for learning Kiro's features and global hooks that apply across all workspaces alongside error handling fixes for all users.

Ask questions about Kiro's features and get accurate answers in-line. The new introspect subagent can explain capabilities, walk you through writing custom agents, hooks, and steering files, and suggest the right configuration for your workflow. Available in V3 (kiro-cli --v3).

Define hooks once and have them apply everywhere. Hooks placed in ~/.kiro/hooks/ now fire in every workspace automatically, so cross-cutting behaviors like linting on save, security checks before commits, or custom approval gates no longer need to be duplicated per project. Workspace-level hooks continue to work alongside global ones. Available in V3 (kiro-cli --v3).
