feat(canvas): warm-paper theme + Tailwind v4 migration

Brings the canvas onto the warm-paper design system already shipped to
landing, marketplace, and SaaS surfaces, and migrates the build from
Tailwind v3 → v4 to match molecule-app.

Plumbing:
- swap tailwindcss v3 → v4, drop autoprefixer, add @tailwindcss/postcss
- delete tailwind.config.ts (v4 reads tokens from @theme blocks in CSS)
- globals.css: @import "tailwindcss" + @plugin "@tailwindcss/typography"
- two @theme blocks: warm-paper light defaults + always-dark surface
  tokens (bg-bg / ink-mute / line-strong) for terminal/console panels
- [data-theme="dark"] cascade overrides the warm-paper tokens for dark
- React Flow edge stroke + scrollbar + selection colour pull from
  semantic tokens so they flip with the theme

Theme infra (ported from molecule-app, identical contracts):
- lib/theme-cookie.ts: mol_theme cookie + boot script (no "use client"
  so server components can read the constants)
- lib/theme-provider.tsx: ThemeProvider + useTheme + cookie writer with
  Domain=.moleculesai.app so the preference follows the user across
  canvas/app/market/landing subdomains AND tenant subdomains
- lib/theme.ts: ColorToken union + cssVar() helper
- components/ThemeToggle.tsx: 3-way System/Light/Dark picker
- layout.tsx: SSR cookie read + nonce'd inline boot script (CSP needs
  the explicit nonce — strict-dynamic doesn't forgive an un-nonce'd
  inline sibling) + ThemeProvider wrapper + bg-surface/text-ink body

Component migration (62 files):
- Mechanical bg-zinc-* / text-zinc-* / border-zinc-* / text-white →
  semantic surface/ink/line tokens via perl negative-lookahead pass
  (preserves opacity modifiers like /80, /60)
- bg-blue-500/600 → bg-accent / bg-accent-strong
- text-red-* / amber-* / emerald-* → text-bad / warm / good
- Tinted-state banner backgrounds (bg-red-950, bg-amber-950, bg-blue-950
  etc.) intentionally left literal — they remain readable on warm-paper
  in light mode without inventing new state-soft tokens
- TerminalTab.tsx skipped — xterm renders to canvas, not DOM
- 3 unit-test assertions updated to match new token strings (credits
  pillTone, AuthGate overlay class, A2AEdge accent)

Verification:
- pnpm test: 1214/1214 pass
- pnpm tsc --noEmit: clean
- next build: ✓ Compiled successfully (8 routes)
- dev server inspection: html data-theme stamped, body uses
  bg-surface text-ink, boot script carries nonce, compiled CSS
  contains both @theme blocks + [data-theme="dark"] override
