v1.2.2: Add Healthcare specialization, mark cancelled courses, rename Digital Marketing

Browse Source 
Apply the J27 (5/6/2026) Stern specialization sheet:

- Add Healthcare (HCR) as the 15th specialization, with HCR cross-listings on
  spr2-health-medical, spr3-analytics-ml, sum2-social-media (renamed), and
  fall1-managing-change. 10 credits available, no required-course gate.
- Rename sum2-social-media to "Digital Marketing Strategy in Practice";
  replace its description with new MSKCC-anchored content; clear instructor
  pending confirmation of new lead.
- Switch from delete-and-replace to the previously-unused cancelled flag
  (Approach B): mark spr5-customer-insights cancelled, add Managing Growing
  Companies back to Summer Set 2 as a cancelled placeholder per the printed
  sheet.
- Update data integrity tests: course count 46 -> 47, spec count 14 -> 15;
  per-spec "across sets" helper now filters cancelled courses so future
  cancellations trigger an obvious assertion failure (BRM 6 -> 5,
  MKT 7 -> 6, HCR 4 new).
- Replace hardcoded 14 in optimizer.test.ts with SPECIALIZATIONS.length.

# Changelog
## v1.2.2 — 2026-05-09
### Changes
- **Healthcare specialization (HCR)** — added 15th specialization, Healthcare; qualifies via The Business of Health & Medical Care (Spring Set 2), Analytics & Machine Learning for Managers (Spring Set 3), Digital Marketing Strategy in Practice (Summer Set 2), and Managing Change (Fall Set 1); 10 total credits available, no required course gate
- **Course rename** — "Social Media and Mobile Technology" renamed to "Digital Marketing Strategy in Practice"; description replaced with new MSKCC-anchored content covering digital strategy and agentic AI; instructor cleared pending confirmation
- **Cancellations (Approach B)** — switched from delete-and-replace to flagging cancelled courses with `cancelled: true`. "Customer Insights" (Spring Set 5) is now marked cancelled. "Managing Growing Companies" reappears in Summer Set 2 as a cancelled placeholder per the J27 sheet
- **Reachability test** — `data.test.ts` now excludes cancelled courses when counting per-spec set reachability, so future cancellations are caught by an obvious assertion failure
