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

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.

At senior management levels today, digital fluency is expected. Business leaders know where to focus their teams, what to prioritize, and where customer understanding driven by agentic AI can create competitive advantage.\n\nThe course centers on live engagement with the senior digital strategy team at Memorial Sloan Kettering Cancer Center - one of the top two cancer centers in the country. Teams will develop and present a digital strategy that encourages patients under the age of 40 to seek their care at MSKCC.\n\nYou\'ll build a practical framework connecting segmentation, positioning, content, channels, platforms, AI, and performance measurement. Increasingly, this includes agentic AI - systems that don\'t just generate outputs, but act: orchestrating journeys, adapting content in real time. The challenge is not access to these capabilities but knowing where and how to deploy them for impact.\n\nTara Liggins, VP of Engagement at L\'Oréal, will join several sessions to show how digital strategy translates into digital tactical engagement. Dr. Nnamdi Ezeanochie, a thought leader at Google Gemini will lead a session on how all aspects of AI is reshaping strategy - from passive tools to systems that act, decide, and optimize.\n\nBy the end of this course, students will not just understand digital strategy. Importantly, they will leave with the confidence and judgment to LEAD cross-functional teams, influence executive stakeholders, and drive digital strategies that don\'t sit on slides - but get funded, implemented, and deliver results.',
