Implemented and merged in PR #105 (3b07d1d).
- Added a shared
sprint-issue-count-badgethat reuses the existing compact count-badge styling. - Active, planned, and historical sprint totals now render
0 Issues,1 Issue, orN Issues. - Existing active column counts, history outcome counts, total sources, and lazy-loading behavior remain unchanged.
- Documented the component and added render coverage for 0, 1, and multiple issues in every sprint state.
Verification: focused render tests and make test passed, uiSprintIssueCount has 100% statement coverage, and both GitHub CI jobs passed.
