L'électron rare

Hand-write the intro and outro arc for each of the 28 morceaux (56 new independent arc functions). intro = voices enter across the 64 bars (sparse->full, capped at the plateau with a light O lead-in into live); outro = voices exit (full early, dropping out toward the break/outro). Approach: - one arc_intro_<m> / arc_outro_<m> per morceau, registered in INTRO_ARCS/OUTRO_ARCS; composed from the primitive fill/hit grid API over the I/B/R/D/P/K/O section codes. - the 7 breaks morceaux share a _breaks_intro/_breaks_outro shape parameterized per morceau (deviation from "fully independent" - flagged for review). - test_sections.py gate: intro builds, outro breaks down, live densest - all 28 PASS. Impact: 84 presets regenerated, VALIDATE PASS 84/84. Section feel is shape-correct; musical review by ear pending.
