refactor(cli): parse sqb arguments natively (#1096)

* refactor(cli): parse sqb arguments natively with argparse-compatible output

Move argv parsing, help/usage/error formatting and parse_cli_invocation's
post-parse rules into a Rust argv domain in sqlbuild-cli, driven by an
embedded command table, and expose it through _native.parse_cli_arguments.
Delete the Python argparse parser, its argument helpers and the coded
parser class.

* fix(cli): track the embedded sqb command table outside the ignored data directory

* chore: update the Python boundary ratchet
