feat(skills): /new-project 4-phase pipeline
Hub-and-spoke orchestrator for RULE 0.12 at project scale. SKILL.md
indexes 4 phase files: intake, fork-skeleton, parallel-exec, merge-
ceremony.
Flow:
Phase 1 — 1 free-text line (GOAL) + 1 batch of 5 AskUserQuestion
(type, theory, fanout, main-agent, DB mode).
Phase 2 — project/<slug> branch, kei-ledger fork root, theoretical
sub-agent spawn confirmation click.
Phase 3 — poll kei-ledger list --status running, aggregate
progress.json, steering click (continue / add / kill /
merge / pause).
Phase 4 — kei-ledger validate per bundle, per-branch merge verdict
click (merge --no-ff / squash / reject / defer), final
integration + NO-DOWNGRADE close click if any rejected /
deferred.
>=6 AskUserQuestion calls minimum (1 batch Phase 1 + 1 Phase 2 + 1
Phase 3 + >=2 per-branch Phase 4 + 1 close).
Constructor Pattern: SKILL.md 109 LOC, phase files 80-108 LOC each —
all under 150 LOC.
