Sequences: chains of moves in the studio, with a fits-after clip picker

[sp00ktober]

Phase 1 of the moveset editor: clips that belong together become a sequence.

• Sequences:
  • A sequence is a chain of moves through Move.after; the manifest is unchanged.
  • mhfu_port.sequence finds the chains.
  • The Moves dock groups its table by sequence and edits a chain as a strip: add a step, change a step's clip, remove, earlier, later, split.
• Fits after:
  • mhfu_port.continuity scores how well one clip's first pose continues another's last pose. The score is the mean joint rotation with the heading removed: good at 10° or less, fair at 20° or less.
  • The step picker ranks clips by that score, or by source number.
  • The Clips dock can sort by the score and shows which moves use each clip.
• Play sequence: plays the chain in the viewport, each step starting where the last one ended. The Timeline shows the steps as a bar.

On the Zinogre donor:

• Each backflip part ranks first after the part before it.
• flinch_roll_left_part_1 continues into flinch_roll_right_part_2 (4.4°), not into left_part_2 (42°), so the two part 2 labels look swapped.
• horn_smackdown_front_part_1 ends in a pose no clip starts from (best 38°).

Tests: 2589 passed with game data; CI's test job passes in a Linux container.
