URL: https://github.com/apache/superset/pull/44185

   ### SUMMARY
   
   `charts_attached_to_dashboard` returns `[attach, detach)` attachment 
**windows** in transaction-id space — one entry per attachment episode, for 
every chart that has **ever** been on the dashboard — not present membership. 
The name read as a membership query, and that misreading is the common root of 
three M2M-shadow bugs (sc-119770, sc-119907, sc-120007).
   
   This renames it to `chart_attachment_windows_for_dashboard` across all 17 
references (`superset/versioning/` + tests) and rewrites the docstring so the 
summary line states the history-not-membership contract outright. Mechanical 
rename; **no behavior change** — no call site's logic is touched.
   
   ### BEFORE/AFTER SCREENSHOTS OR ANIMATED GIF
   
   N/A — internal rename, no UI change.
   
   ### TESTING INSTRUCTIONS
   
   ```bash
   pytest tests/unit_tests/versioning/   # 152 passed
   grep -rn "charts_attached_to_dashboard" superset/ tests/   # empty
   ```
