Fix review findings: quoting, set -e trap, system path, push guard

- Quote all $DEFAULT_OUTPUT_DIR references to handle paths with spaces
- Replace git rev-parse $(...) with exit-code check to avoid set -e trap
- Fix system file dst using $i instead of ${i#/} (double-slash bug)
- Quote $i in beginswith call
- Simplify push guard to check remote existence directly
