- Added `set -euo pipefail` to ensure the script exits on errors, undefined variables, or failed pipelines. - Enhanced error handling for SSH agent start and key addition, with clear error messages. - Replaced `echo` with `printf` for more reliable and formatted output. - Introduced optional legacy RSA hostkey handling based on input parameters. - Improved overall script readability with clearer variable names and structured conditionals.
