Final PR: #349.
What this implements
Extends align_phases() with amplitude-product or explicit uniform weighting, paired Weight-typed FOM columns, intensity-to-amplitude conversion, and opt-in hand inversion. Hand search remains off by default and separate from proper reindexing.
When hand inversion or an origin shift is selected, all Phase and complex columns are transformed consistently in the returned copy.
Tests
Tests cover FOM multiplication and range checks, paired FOM keys, intensity equivalence, opt-in hand selection, complex-column recovery, and the default proper-hand behavior.
