Pull Request Overview

This PR improves the console output experience when running Aspire apps by styling apphost logs with a faded appearance and displaying dashboard/codespaces URLs in green in the console. The changes enable passing text styling information through the CLI-to-extension backchannel and apply ANSI escape codes for formatting.

Key changes:

• Added textStyle parameter to the backchannel message writing pipeline to support ANSI escape codes
• Applied dim styling (\x1b[2m) to apphost logs and green styling (\x1b[32m) to dashboard/codespaces URLs
• Conditionally hide dashboard URLs in the CLI UI when running in extension host mode
