base-bash-libs v0.2.0

Added

• Added std_run as the preferred command-runner API while retaining run as a compatibility wrapper.
• Added readonly BASE_BASH_LIBS_VERSION, sourced from the package VERSION file when lib_std.sh loads.
• Added optional --fetch support to check_script_up_to_date.
• Added Linux and supported-Bash GitHub Actions validation coverage.
• Added PTY-backed coverage for wait_for_enter.
• Added non-Homebrew installation documentation.

Changed

• Preserved target file modes when update_file_section appends or replaces managed sections.
• Hardened update_file_section marker ordering and edge-case behavior.
• Validated variable-name arguments consistently across stdlib and git helpers.
• Respected NO_COLOR and composed structured log records before one final stderr write.
• Made safe_mkdir, git_get_current_branch, and git pull retry behavior more explicit.

Fixed

• Failed cleanly when lib_std.sh is sourced by unsupported Bash versions.
• Returned nonzero from set_log_level for invalid input without changing existing logger levels.
• Added explicit dependency guards for companion libraries sourced without the stdlib.
