Motivation and Context

Color Progress Output Mode

Adds a color progress output mode (--progress color) that renders ANSI-colored progress output with visual differentiation between progress states.

Unlike the existing ansi mode (which only uses cursor control), color introduces color-coded output:

• Cyan → spinner / active tasks
• Bold text → task description
• Yellow / Green → percentage (in-progress / complete)
• Green → progress bar
• Dim text → secondary information

Like ansi mode, this feature requires a TTY.

Closes #1366

Testing

• Tested locally
• Added/updated tests
• Added/updated docs

@jglogan PR 2/2 for the Color/Plain Progress Output Mode set (following #1365). I think this is in a good place now would appreciate some eyes when there is a free moment.

-cc @dkovba (since you approved the Plain PR #1367 & have some context)

Thank you both for all the help and support!

p.s - as a Canadian, the way you guys spell colour trips me out 😛
