chore: forge migration git.cloudinit.dev -> git.coreci.dev

---ci---
phase: 7
milestone: v0.2
status: complete
---/ci---

Forge hard-cutover verified: old host TLS-dead, new host serving
repo with full history; coreci-bot token valid (push+admin);
all 12 releases migrated with IDs intact (#847-#864, v0.0.1-v0.2.2).

- config.json: release.base_url -> https://git.coreci.dev
- PROJECT.md: D-006 decision row records the migration
- origin remote URL updated (git remote set-url)
- local credential helper (.ciagent/bin, gitignored) now matches
  both hosts — new primary + legacy for older checkouts

 | D-003 | TypeScript monorepo (pnpm/turborepo) + Next.js | Unified codebase for all 4 surfaces. Shared component library, types, mock data. Next.js App Router for route-based surface separation. Python AI services deferred to later milestones. | Monorepo structure with apps/web + packages/* |
 | D-004 | All 4 surfaces in v0.1 (Learner, Marketplace, Employer, Admin) | Founder selected all 4 surfaces for the prototype. Complete product visualization before any backend work. | 24 REQ-IDs covering all surfaces + shared infrastructure |
 | D-005 | High-fidelity interactive prototype | Founder selected high-fidelity over wireframes. Realistic mock data, navigation flows, responsive layouts, component library. No backend calls. | Clickable prototype with realistic content |

 | D-009 | AI tutor UI as chat interface mockup with pre-scripted responses | The learner surface includes an AI tutor chat UI mockup. No real AI backend — pre-scripted responses simulate the Coach and Tutor agents. | Mockup only in v0.1, real agents in future milestone |
