chore(progress)!: migrate progress to lipgloss (#676)

* chore(progress)!: migrate progress to lipgloss

This removes the dependency on termenv and replaces it with lipgloss. This
change also removes the WithColorProfile option, as it is no longer needed.
The new API uses `color.Color` types for colors, which are more flexible and
allow for more advanced color manipulation.
