Add Makima iOS app scaffold (M0 + M1 design system)makima-ios-scaffold

Pure-native SwiftUI client for makima.jp under makima/ios/.

M0 (scaffold)
- XcodeGen project (iOS 18+, Swift 5.10, bundle co.soryu.makima)
- Makefile targets: bootstrap, xcgen, ios-sim-fast, ios-device-fast, test, lint
- GitHub Actions workflow ios-ci.yml — builds + runs XCTest on macos-14
- MIT repo root license already in place

M1 (design system, web-aesthetic port)
- Palette: #0c1729 background, #9bc3ff accent, #3f6fb3 border (ported from Tailwind)
- Typography: SF Mono for chrome, uppercase tracked nav labels
- Components: DashedBorder, GridOverlay, MastheadBar + WebSocketStatus pill,
  NavStripPlaceholder (NAV// prefix), JapaneseLongPressText (mobile analogue
  of JapaneseHoverText), Logo (reuses frontend/public/logo/makima-logo.svg with
  Canvas concentric-ring fallback), Badge
- RootView demo screen: masthead, nav strip, logo, CONTROL SYSTEM badge,
  SYSTEM// status card, GLOSSARY// card with 命令/契約/聴取/史料 long-press terms

Auth (v1 plan, not wired here): x-makima-api-key header — verified against
src/server/auth.rs. Authorization: Bearer reserved for v1.1 Supabase OAuth.

v1 plan doc: makima/ios/docs/ios-v1-plan.md
Not in this PR: networking, WebSocket client, stores, feature surfaces
(Home/Contracts/Tasks/Directives/Daemons/Listen), notifications. Those land
across M2-M8 per the plan.
