feat(plugin): add optional askPermission to ToolContext

[nielpattin]

Add optional askPermission to plugin ToolContext

Summary

• Plugins can now call ctx.askPermission() to request user confirmation before sensitive operations
• Made the property optional to avoid breaking existing plugins

Details

This hooks into the existing Permission.ask() system so plugins get the same permission UX as built-in tools.

Example usage in a plugin:

execute: async (ctx, input) => {
  if (ctx.askPermission) {
    await ctx.askPermission({
      tool: "dangerous-tool",
      message: `About to delete ${input.path}`,
    })
  }
  // proceed with operation
}

Testing

• Existing plugins (without askPermission) still work
• New plugins can opt-in to permission prompts

Checklist

• Types are backward compatible (optional property)
• No breaking changes for existing plugins

Demo:

(Ignore the skill tool mention, it's just a plugin that use the same format as the native skill support)
