Traction figures out of date (weekly check) #1314

The weekly check_traction.py --live run found figures that differ from GitHub or from each other:

• contributors: README.md (External Contributors) says 61, GitHub says 64
• forks: README.md (Forks) says 74, GitHub says 77
• contributors: ROADMAP.md (Current traction, contributors) says 61, GitHub says 64
• forks: ROADMAP.md (Current traction, forks) says 74, GitHub says 77
• contributors: METRICS.md (badge Contributors) says 61, GitHub says 64
• forks: METRICS.md (badge Forks) says 74, GitHub says 77
• forks: METRICS.md (latest weekly row, 2026-W45) says 74, GitHub says 77
• contributors: METRICS.md (latest weekly row, 2026-W45) says 61, GitHub says 64

Update the figures in README.md, ROADMAP.md and METRICS.md together, then run python3 scripts/check_traction.py --live. This issue closes itself on the next weekly run once they match.
