Module output 

Terminal-aware presentation for haz run.

The module groups four concerns:

• color_choice detects whether the live process should emit ANSI colour sequences (both streams must be terminals AND NO_COLOR must be unset / empty).
• palette derives a deterministic 24-bit RGB colour for each haz_domain::task_id::TaskId and supplies the small ANSI-escape helpers.
• duration formats a std::time::Duration in the 176ms / 7s 856ms / 1m 23s / 1h 23m grammar both the per-task summary lines and the run-level epilogue use.
• presenter implements haz_exec::presenter::TaskPresenter against those primitives.

The haz-exec crate stays terminal- / colour-agnostic. Pulling this presenter through the existing TaskPresenter port is the single integration point: the binary picks the presenter at startup and feeds it into the observer it hands the scheduler.

Modules

color_choice

Auto-detection of whether haz run should emit ANSI colour escape sequences.

duration

Human-readable Duration formatting for the per-task summary lines and the run-level epilogue.

epilogue

Run-level summary emitted after the scheduler returns.

palette

Deterministic per-task colour assignment plus the small ANSI escape-code helpers the presenter writes.

presenter

haz run’s TaskPresenter implementation: colour, glyphs, and per-task duration in summary lines.
