Merge origin/main, resolve CHANGELOG conflict, bump to v0.13.7.0

Main landed v0.13.6.0 (GStack Learns) while this branch had v0.13.6.0
(Community Wave). Resolved by keeping both entries and bumping this
branch to v0.13.7.0. Regenerated SKILL.md files to pick up new learn
skill and apply the find -exec rm fix from this branch.
