The fix adds `rm -rf .git &&` to both fallback scripts, which ensures that any existing `.git` directory is removed before attempting to initialize a fresh repository.\n\nLet me write a summary of the changes:\n\n## Summary\n\nI've successfully fixed the GitHub issue related to git clone failures when the destination directory is not empty.\n\n### Problem\nWhen Fabro's SSH and EXE sandboxes attempted to clone a repository into a non-empty directory, the initial `git clone` command would fail with:\n```\nfatal: destination path '.' already exists and is not an empty directory.\n```\n\nThe fallback mechanism would then run `git init && git remote add origin ... && git fetch origin && git checkout ...`, but this could fail if:\n1. A `.git` directory already existed from a previous failed clone attempt\n2. The `git remote add origin` would fail because a remote already existed\n\n### Solution\nAdded `rm -rf .git &&` to the beginning of the fallback script in both:\n1. `lib/crates/fabro-ssh/src/lib.rs` (line 212)\n2. `lib/crates/fabro-exe/src/lib.rs` (line 281)\n\nThis ensures:\n1. Any existing `.git` directory is cleaned up\n2. `git init` starts with a clean slate\n3. `git remote add origin` succeeds without conflicts\n4. The clone/checkout operations complete successfully\n\nThe fix is minimal, focused, and handles the edge case where previous clone attempts left behind a `.git` directory that would interfere with subsequent attempts.",
