v1.11.0

Added

• stack [file] [--unset] — set or show the default stack file for subsequent commands (like oc project). No args prints the current path; a path is stored as an absolute path in $XDG_CONFIG_HOME/containerctl/config.json; --unset clears it. Explicit -f/--file still overrides the saved default for that invocation. Resolution order: -f → saved stack path → ./stack.yaml.
• command and entrypoint accept a Compose-style string as well as a list. A string is shell-split into argv (quotes and backslashes supported); it is not run by a shell. Example: command: serve --port 8080 is equivalent to command: ["serve", "--port", "8080"].

Changed

• Removed the version subcommand. Use containerctl --version instead (prints version, build date, Go version, OS/arch). Engine reachability details are no longer included.
