fix(deploy): resolve shellcheck SC2235 warnings in conditional expressions

Replace subshell grouping with bash compound conditionals for better
performance and to satisfy shellcheck SC2235.

Changed:
- ([ condition ] || [ condition ]) → [[ (condition || condition) ]]
- Use [[ ]] instead of [ ] for compound conditionals
- Eliminates subshell overhead in deployment status reporting
