Add an HTML title attribute to the result table's column headers in the Web UI (play.html). When a column is narrow, its header name gets truncated; now hovering over the header shows the full column name and type in a tooltip.

The result table's column headers can be truncated when the column is
narrow. Add an HTML `title` attribute so hovering over a header shows the
full column name and type.

AI Review

Summary

This PR adds a native HTML tooltip to Web UI result-table headers in programs/server/play.html, so hovering a truncated column header shows the full column name and type. I did not find any actionable correctness, regression, or PR-metadata issues in the current diff, and the green CI state is consistent with the change's limited scope.

Final Verdict

✅ No actionable findings.

Updating the branch to fix the 03532_window_function_and_null_source_max_threads test, which was broken today in master.
