Summary

• pass --end-of-options to git show before the project-config revision
• cover bare repositories whose configured default branch starts with -

Problem

When no worktree has the default branch checked out, Worktrunk reads the committed .config/wt.toml with git show <branch>:.config/wt.toml. Git parses a revision such as -x:.config/wt.toml as an option. The best-effort fallback then returns no project config, so hooks, aliases, and other project settings disappear without an error.

Tests

• Confirmed the new integration test failed before the fix with project.config = null.
• Confirmed the targeted test and the adjacent object-store fallback test pass after the fix.
• Ran PATH=/opt/homebrew/bin:$PATH mise exec rust@1.97 -- cargo run -- hook pre-merge --yes: 4,968 tests passed and 1 skipped; fmt, clippy, rustdoc, and doctests passed.
