fix: remove -w short flag from --workspace to resolve collision with --web

The -w short flag was registered on both the global --workspace option
and the command-level --web option. Since Cliffy resolves global options
first, -w always mapped to --workspace, making --web unusable (both as
-w and --web due to prefix matching).

Remove the -w alias from --workspace so that -w correctly maps to --web
on commands that support it. Users can still use --workspace in full.

Fixes #174
