- Around line 229-242: Update OutputHandler::task_prefix_color to return an
empty string immediately when self.quiet(Some(task)) is enabled, before
resolving the replacing renderer or evaluating color support. Add a regression
test covering task_prefix_color with quiet mode enabled, using the
task-execution path rather than only testing the helper.

67-69: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winAssert the ANSI prefix format for all supported modes.
These checks only require a nonempty value. A non-ANSI value would pass, although
MISE_TASK_COLORmust contain an ANSI sequence. Convert each value to hex and assert that it starts with1b5b, as lines 63-65 do for prefix-mode tasks.Also applies to: 73-73

Summary
MISE_TASK_COLORContext
Task prefix colors were deterministic, but the resolved style was internal to mise. Task scripts that wanted matching output had to duplicate the display-name hash, palette, and emphasis rules.
MISE_TASK_COLORnow contains the complete ANSI opening sequence used by the task label, including bold, dim, or bright styling. It is injected per task occurrence as a reserved runtime value, so ambient or configured values cannot make it disagree with the rendered label and a parent task's color does not leak into nested tasks. The value is empty for interleaved, quiet, silent, or raw output and when color is disabled. Replacing output also provides the value through its text fallback because the variable describes the rendered task-label style rather than promising that every output line is prefixed.Verification
