v0.2.0: HEFFT

Highlights

• Adds built-in scalar HEFT support and trusted UFO HEFT workflows across pyAmpliCol execution modes.
• Adds exact symmetric-group FFT full-colour contraction.
• Adds helicity-parametric recurrence and on-the-fly scheduling.
• Adds a resumable profiling workflow for selected-helicity and complete-helicity-sum comparisons, including optional AmpliCol, standalone FFT, and MadGraph references with anytime PDF rendering.

The name HEFFT celebrates the combination of new HEFT UFO-model support and the new FFT colour-contraction mode.
