spike: institution grouping helper for fall datathon (shared SIS + shared goal)

[William-Hill]

Context

From AASCU Intermediary feedback session (see docs/aascu_intermediary_feedback_summary.md, pain point F):

"We definitely have a list of what the SIS is for each individual institution... I would maybe err on the side of which one is the most common, maybe more so on which campuses have the most need."

"We have themes of types of goals and institutions... it's important in a good way to cross-talk that to identify the sorts of goals that would be to focus on which ones are using this SIS and which ones have similar goals. The most common example would be advising."

Last year's datathon ran into trouble because three participating institutions had wildly different SIS and goals — most of the day was spent finding common ground. Grouping institutions by both shared SIS and shared institutional goals (e.g., "advising") produces stronger cross-talk and better outcomes.

Goal

Operational artifact (not a user-facing feature): a candidate grouping of institutions for the fall datathon, organized by shared SIS + shared institutional goal.

Scope

• Pull SIS-by-institution list from AASCU
• Cross-reference with each institution's stated programmatic goals
• Output a table / matrix of candidate cohorts (e.g., "Banner + Advising", "Workday + Retention")
• Rank by (a) cohort size and (b) demonstrated need

Out of scope

• Building this as a tool feature — this is research / planning output for the datathon team

Deliverable

• Markdown doc at docs/datathon_institution_grouping.md with the candidate cohort matrix
• List of recommended groupings + rationale for each
