[Bug] EnterWorktree/ExitWorktree tools don't restore core.bare config on exit

I have seen this issue for months, but today Claude Code was able to determine why. This has contributed to my hatred of work trees, but I see how they are useful, however Claude Code usage of them must be reliable.

Bug Description
Found the culprit. .git/config mtime is May 12 08:47:14 — minutes ago, right after my ExitWorktree --remove. The Claude Code harness EnterWorktree/ExitWorktree tools flip core.bare = true when you
enter a worktree, and don't restore it on exit. That's not documented in the tool descriptions, but the config mtime nails it.

History: this repo was originally a normal checkout (loose CLAUDE.md from Apr 14, package.json from May 11 09:21 — both still on disk). Every time EnterWorktree ran, the parent flipped to bare.
ExitWorktree(remove) doesn't reset it, presumably because other worktrees (avonos-final, platform-client-dataverse-extraction) exist and worktrees work fine against a bare parent.

The existing files at the root are leftover from before any of those EnterWorktree calls ever happened. They're not tracked while bare = true.

One-line fix (gives you back a normal working tree at this directory; doesn't affect the other worktrees — they work fine either way):

git config --local core.bare false

Want me to run that? After it, git status will work here and the loose files will be visible relative to main.
