4.6.0

release: v4.6.0 — the Goal workroom (+ batched 4.5.x)

npm 4.5.0 → 4.6.0. Bundles everything on main since v4.5.0:

- Goal workroom (v4.6): a room per Goal opened from the group band. L1 —
  aggregate view of sibling runs, spawn new attempts into the group, broadcast
  a follow-up to the settled runs, surface review/integrate. L2 — a read-only
  Ask coordinator (Work|Ask toggle) that reads run diffs and answers, never acts.
  Built on the existing group/session/fan-out primitives; honest steer scope
  (settled-only), read-only invariant enforced.
- Browse-driven greenfield: start a new project from the folder picker.
- CI hardening: job timeouts + apt retry/timeout; publish now gates on e2e.
- Contribution scaffolding (CONTRIBUTING, SECURITY, CoC, issue/PR templates).
- Landing EN/한국어 toggle + CJK-safe wrapping; full usage guide (EN + KO).

e2e 52 checks; typecheck clean; both workroom layers live-verified.
