Apply automated fixes from shellcheck and shfmt to all shell scripts:
- Quote variables to prevent word splitting and globbing
- Use $(...) instead of backticks for command substitution
- Add proper shebang and set -euo pipefail where missing
- Fix array handling and iteration patterns
- Consistent indentation (4 spaces)
- Remove unnecessary curly braces and simplify expressions
Files fixed:
- deployment/*.sh
- scripts/*.sh
- orchestrator/scripts/*.sh
- fuzzer_runner/runner.sh
- protoc.sh
