feat(team-leaderboard): Add achievement badges and ranking system for team members

Mohana Sri Bhavitha requested to merge badges/bhavitha into feature-final

This merge request introduces a gamification system to the Team Leaderboard feature by adding achievement badges and ranking徽章 (badges) that recognize individual and team performance.

Changes Made

1. New Badge SVG Assets (assets/badges/)

2. Modified modes/team_leaderboard.py

New Functions:

  • _build_individual_rows(team_data) – Flattens all team members into a single ranked list and assigns achievement badges
  • _load_rank_badge_svg(rank) – Loads SVG markup for rank badges (1-6) from multiple fallback directories
  • _load_individual_badge_svg(badge_name) – Loads SVG markup for achievement badges

Badge Assignment Logic:

  • Maximum 3 badges per member
  • Team Player: Highest scorer in each team receives this badge
  • Sprint Star: Member with highest overall score
  • Top Committer: Member with most total commits
  • Merge Master: Member with most merged MRs
  • Hackathon Hero: Member with highest combined total (commits + MRs + issues)
  • Consistency Champ: Member with lowest variance in activity (most consistent)

Rendering Updates:

  • _build_ranking_rows() now includes rank badges in the team ranking display
  • Updated table rendering with custom HTML/CSS for badge visualization

Score Formula

The existing score formula remains unchanged:

score = (total_commits × 1) + (merged_mrs × 5) + (total_mrs × 2) + (issues_closed × 3)

Testing

Test coverage added in tests/test_modes_team_leaderboard.py for:

  • Badge row extraction and aggregation
  • JSON validation
  • Badge loading functions
  • Individual member row building with badges

Breaking Changes

None. This is a backward-compatible enhancement.

Target Branch: feature-final
