kei-fork collect v0.31.0 left `.DONE` + `.KEI_FORK_META.toml` in the
merge. These are per-fork control files, not source of truth. Removing
from main + adding to .gitignore. Also gitignoring `.claude/forks/`
which is the live fork worktree root.
Next kei-fork iteration (v0.31.2) should either:
- (A) strip these files before `git add -A` inside collect, OR
- (B) add them to the repo's .gitignore on `kei-fork create`.
(A) is cleaner — fixed in follow-up.
