Removing a path inside the jail

When to use

• Tearing down a generated artefact after use.
• Resetting a workspace directory before re-bootstrapping it.
• Dropping a temp file once a flow no longer needs it.

Notes

• Symlinks are removed by themselves, not their targets. recursive does not change that.
• There is no trash bin; this is unlink(2) / rmdir(2). Confirm caller intent before invoking.
• removed is always true on success. Missing paths return Err(S211); non-empty directories without recursive: true return Err(S214); permission errors and other I/O failures come back as the trigger Err with the corresponding FsError shape.
• Same jail and denylist rules as shell::fs::ls.
