Add --version to all con-duct subcommands

[Copilot]

--version only worked for con-duct (top-level) and con-duct run/duct, but failed on ls, pp, and plot subcommands with "unrecognized arguments: --version".

Changes

• cli.py: Moves --version from _create_run_parser() into _create_common_parser(), which is already used as a parent for all subcommands — eliminating duplication and giving every subcommand --version for free
• test_cli.py: Adds a parametrized test covering --version on all four subcommands

$ con-duct ls --version
con-duct ls 0.9.0
$ con-duct pp --version
con-duct pp 0.9.0
$ con-duct plot --version
con-duct plot 0.9.0

@copilot I do not see test to test con-duct --version itself. Add parametric empty string here or make commands into the lists and add empty list to concatenate for check_output?

[Copilot]

Done — merged test_con_duct_version and test_con_duct_subcommand_version into a single parametrized test with None for the top-level con-duct --version case (commit 9a7e26a).

Pull request overview

This PR fixes inconsistent CLI behavior by making --version available on every con-duct subcommand (not just the top-level command and run), and adds tests to prevent regressions.

Changes:

• Add --version to the shared/common argparse parent so all subcommands inherit it.
• Remove the now-redundant --version definition from the run-specific parser.
• Add a parametrized CLI test to validate --version works for con-duct, run, ls, pp, and plot.

I looked into this. The bigger problem with using the common parser would be that it adds --log-level and --quiet to the main command, which wouldn't be that bad except the args dont get passed to the subparsers. So a user could do con-duct --log-level DEBUG run sleep 1 which would use default log-level INFO.

IMO extra machinery just to avoid a 1 line fstring is overkill.
