5.0.0

release: v5.0.0 — the console redesign

npm 4.8.0 → 5.0.0. The major bump: the left rail stops being a permanent compose
form and becomes a navigator; launching is a focused action.

- Navigator rail — machine switcher + a scannable repo list with live active-run
  counts + attention dots, click-to-scope the board, and the Active/Goals/Archive
  view nav (moved out of the header).
- Launch as a New sheet — ＋ New opens a focused Task/Goal/Workbench sheet with
  progressive Options (model/design/deliverables); footers adapt (Run fleet /
  Plan & run / Open workbench).
- Pocket board — the mobile drawer is just the navigator + a ＋ FAB opens the
  sheet; killed the left-right jitter (root overscroll/overflow-x clamp) and fixed
  mobile-Safari login (real form-POST navigation → 303, no more cookie race).
- Compare AI review now has full-height scrollable room (toggle in place of the
  diff columns) instead of a squeezed band.
- English sweep of the deliverables/contract/converge labels.

Core (rail → sheet → mobile + compare fix) shipped; ⌘K palette / collapsible rail
/ split menu trail into 5.0.x. e2e 77; typecheck clean; every phase live-verified.
