refactor: improve install-ignity.sh code quality
- Remove unused RELATIVE_DIR and BASE_PROJECT variables - Remove unused env::get function (called undefined log::fatal) - Fix grep output leak: add -q flag to suppress stdout - Replace env::get_or_empty subshell calls with ${VAR:-} in hot path - Simplify runtime::try by removing redundant status check - Wrap pkg::install in subshell to avoid working directory drift - Consistent function declaration style (remove parentheses from pkg::install) Eliminates ~96 unnecessary subshells during Docker build phase.
