Rip out Theia, bump submodules, retire platform/ scaffold, snapshot docs + design assets

Theia rip-out (parent):
- Remove theia submodule entry (the local fork, Gitea repo, Coolify app,
  Cloud Run services, and Artifact Registry image are all gone)
- Drop README.md + INFRASTRUCTURE.md (obsolete "Project OS" snapshots
  that also leaked API tokens) and setup.sh (Theia clone bootstrap)
- Delete UI-DESIGN-GUIDE.md, BACKEND_AGENTS_PLAN.md, VIBN_BUILD_PLAN.md,
  VISUAL_EDITOR_PLAN.md, core-packages.md, ai-packages.md, tools-list.md
  (all 100% Theia-specific or superseded)
- Surgical scrubs of remaining Theia mentions in
  AGENT_EXECUTION_ARCHITECTURE.md and TURBOREPO_MIGRATION_PLAN.md

Submodule bumps:
- vibn-agent-runner: Theia rip-out + MCP refactor (api/wrapper/server
  pattern across shell/file/git/memory/prd/search/agent/gitea/coolify)
- vibn-frontend: Theia rip-out + P5.1 attach E2E + Justine UI WIP

Retire platform/ scaffold:
- Remove platform/backend/ (control-plane, executors, mcp-adapter),
  platform/client-ide/ (gcp-productos extension), platform/contracts/,
  platform/infra/terraform/, platform/scripts/templates/turborepo/
  (replaced by vibn-agent-runner + vibn-frontend + Coolify direct)
- Drop architecture.md, technical_spec.md, vision-ext.md,
  "1.Generate Control Plane API scaffold.md" (same era)

Docs / planning snapshots (new):
- AI_CAPABILITIES.md, AI_CAPABILITIES_ROADMAP.md
- AGENT_TELEMETRY_STREAMING_PROJECT.md
- VIBN_PRD.md, product-idea-a.md

Design assets (new):
- branding/{coolify,gitea,ux-testing}/ static brand collateral
- justine/ HTML mockups for the new onboarding/build flows
- preview-assist-ui/ Vite scratch app
- master-ai.code-workspace

Infra helpers (new):
- setup-coolify-montreal.sh provisioner
- gitea-docker-compose.yml
- vibn-coolify-schema.sql for the Coolify Postgres extensions
- prd-agent-prompt.pdf, prompt, root.txt, remixed-9edec9e9.tsx scratch
- flatten.sh helper

.gitignore: ignore **/node_modules, **/.next, **/.turbo, **/coverage
