Adds docs/specs/2026-04-11-nexus-layout-overhaul.md defining the
complete layout and information architecture redesign:
- 4-destination primary nav (Assistant, Studio, Projects, Settings)
- 56px left icon rail + 48px top strip as global frame
- Assistant as default landing (full-bleed chat, no side panels)
- Studio as 8-card workshop grid (Convert folded in as 8th workshop)
- Projects with per-project Builder tabs replacing global routes
(Issues, Agents, Gates, Costs, Activity, Org become per-project;
Routines moves to Settings; Goals folds into Overview; Inbox
killed-replaced by assistant dot + cmdK)
- Promote-to-project transition (chat compresses to 30%, brainstormer
rises into 70%, inset shadow ripple, 700ms)
- Voice and Cmd-K as global affordances; ChatPanel/PropertiesPanel
killed as global rails
- Implementation phases 8-16 with parallel subagent dispatch pattern
Also promotes the previously untracked MIGRATION-PLAN.md into the
repo, and extends it with section 8b (structural overhaul summary
table linking to the spec) and section 11 (binding subagent dispatch
pattern for phases 8-16).
Approved 2026-04-11 in brainstorming session; all 25 decisions from
the discussion are captured in spec section 11.
