fix: resolve --format option conflict between global and export subcommand

[ppetru]

Problem

gwcli drive export <file-id> --format csv fails with:

error: required option '--format <fmt>' not specified

The global --format option (json/table/text output formatting) defined on the root program shadows the export subcommand's --format option (csv/xlsx/pdf export format). Commander.js consumes the flag at the root level, leaving the export command's required --format unsatisfied.

Fix

Enable positionalOptions on the root program and passThroughOptions on the drive command group. This tells Commander.js to stop parsing parent-level options once it encounters a subcommand, allowing each subcommand to define its own options without conflicts.

• program.enablePositionalOptions() — root stops consuming options after a subcommand name
• drive.enablePositionalOptions().passThroughOptions() — drive passes unrecognized options through to its subcommands

Testing

Before fix:

$ gwcli drive export <file-id> --format csv
error: required option '--format <fmt>' not specified

After fix:

$ gwcli drive export <file-id> --format csv
Exported to: MAP.csv

$ gwcli --format json drive search "name contains 'test'"
[...]  # global --format json still works
