v1.1.0

Corrective 1.x release for the latest base-bash-libs code line. This release
supersedes the accidental v2.0.0 publication while preserving all launcher and
library changes.

Added

• Added the base-bash launcher for standalone scripts that want the
  base-bash-libs stdlib preloaded from a shebang.
• Added std_run --timeout, --max-attempts, and --retry-delay execution
  policy options for timeout-only, retry-only, and timeout-plus-retry command
  execution.

Changed

• Changed string case and trim helpers to mutate named variables in place
  instead of requiring command substitution.
• Added public assert_variable_name validation for helpers that accept Bash
  variable names.
• Deprecated std_run_with_timeout in documentation for new code; it remains as
  a compatibility wrapper around std_run --timeout.
• Changed cleanup path registration to require absolute paths so exit cleanup
  cannot drift after a script changes directory.
• Changed the Bash timeout fallback to kill TERM-ignoring commands after a short
  grace period.
• Changed list and string array helpers to require caller-declared indexed arrays
  instead of silently coercing scalar variables.
