[rgarcia]

• adds profile options to browsers create
• adds profiles <create|get|delete|list|download> commands

---

TL;DR

Adds CLI commands to create and manage browser profiles, allowing browser sessions to be saved and reused.

Why we made these changes

To fulfill a feature request (KERNEL-229) for saving and managing browser contexts. This allows users to maintain login states, cookies, and other session data across multiple browser instances, streamlining workflows that require persistent authentication.

What changed?

• New profiles command: Added a new top-level profiles command with subcommands for create, get, delete, list, and download.
• Browser creation with profiles: Extended the browsers create command with flags (--profile-id, --profile-name, --profile-save) to launch browsers using a specific, persistent profile.
• Consistent Timestamps: Refactored timestamp formatting across logs, browsers, and app commands to use a new util.FormatLocal utility for consistent local time display.
• Testing: Added a comprehensive test suite for the new profiles command functionality.
