Add tools.list SDK support and bump CLI to 0.0.407

[ryanfolsom]

Add listTools() / list_tools() / ListTools() / ListToolsAsync() methods across all four SDK languages (TypeScript, Python, Go, .NET) to expose the new tools.list RPC from the CLI runtime.

Includes ToolInfo types, client methods, exports, and E2E tests for each language. Bumps @github/copilot from ^0.0.405 to ^0.0.407 which includes the tools.list RPC handler.

Pull request overview

This PR adds support for the new tools.list RPC method across all four SDK languages (TypeScript/Node.js, Python, Go, and .NET). The implementation exposes built-in CLI tools with their metadata, including tool names, descriptions, parameters schemas, and usage instructions. The PR also bumps the @github/copilot dependency from version 0.0.405 to 0.0.407, which includes the underlying tools.list RPC handler.

Changes:

• Added ToolInfo type definitions across all SDKs with consistent JSON field naming (name, namespacedName, description, parameters, instructions)
• Implemented listTools()/list_tools()/ListTools()/ListToolsAsync() client methods with optional model parameter for model-specific tool overrides
• Added E2E tests for each language SDK to verify tools can be listed and contain expected metadata
