Add .github/TEAM_MEMBERS and other files Kilo has deleted to skipFiles
so future upstream merges auto-remove them via git rm instead of
surfacing delete-by-us conflicts that need manual resolution.
Also drop the stale github/.gitignore entry from keepOurs (the file
does not exist in Kilo main; keepOurs was a no-op) and move it to
skipFiles so upstream's copy is dropped on merge instead of added.
