feat(P01): interactive validation + doc updates + multi-project CLI — IDEATE-12,13,14 + MULTI-02,06

---ci---
phase: 1
milestone: v0.10
status: execute
decisions:
  - id: D-083
    decision: Interactive one-at-a-time validation with accept/skip/modify
    rationale: Gives user full control over ideation results
    confidence: 0.87
  - id: D-085
    decision: Ask-after-validation kickoff of run workflow
    rationale: Balances automation with user control
    confidence: 0.85
  - id: D-091
    decision: Full multi-project support with active_projects array + parallel execution
    rationale: User wants complete multi-project capability
    confidence: 0.85
requirements:
  covered:
    - IDEATE-12
    - IDEATE-13
    - IDEATE-14
    - MULTI-02
    - MULTI-06
---/ci---

- IDEATE-12: Interactive accept/skip/modify validation with readline
- IDEATE-13: acceptIdea/acceptIdeas methods update REQUIREMENTS.md and ROADMAP.md
- IDEATE-14: Ask-after-validation kickoff prompt for
- MULTI-02: --project flag accepts comma-separated or 'all' in pre-action hook
- MULTI-06: ciagent status shows active_projects and ideation config
- projects list shows all active projects with multi-marker
- projects set updates both active_project and active_projects
