fix(cli): Expose projectPath/workspacePath as CLI flags for list-schemes (#271)

The session-aware public schema omitted both projectPath and workspacePath,
which are the only parameters for list-schemes. This left the CLI with zero
tool argument flags, making the command unusable without session defaults
or --json.
