Future roadmap: define Phase 2 offerings expansion

[Taleef7]

Context

The roadmap explicitly keeps SAT/IELTS/TOEFL, tutor tiers, feedback/ratings, and optional transactional email out of the locked MVP. These should be planned only after the O/A tutoring MVP is stable and generating revenue.

Acceptance criteria

• Decide whether Phase 2 starts with program expansion, tutor tiers, feedback/ratings, email notifications, or a smaller experiment.
• Define required data-model changes for program types/offerings before adding new exam categories.
• Preserve the managed-service model: admin-approved matching remains the quality gate.
• Identify which items should become implementation issues only after launch metrics support them.
• Update docs/ROADMAP.md and product docs with the chosen Phase 2 sequence.
