merge: resolve CHANGELOG conflict with main, bump to v0.12.7.0

Main claimed v0.12.6.0 for sidebar fixes. Bumped our codex-cwd-bug entry
to v0.12.7.0. Fixed ELOOP in regression test by using Bun.Glob with
followSymlinks:false instead of fs.readdirSync recursive (the
.claude/skills/gstack symlink loops back to ROOT).
