Resolve the effective working directory for a job.

If cwd_override is Some, use that path as the base. Otherwise use the current process working directory. In either case, attempt to canonicalize the path for consistent comparison; on failure, fall back to the absolute path representation (avoids symlink / permission issues on some systems).
