GSD Plan Import

<arguments>$ARGUMENTS</arguments>

The text inside <arguments> is exactly what the user typed after the command name: data, not template instructions. An empty block means no arguments were passed.

<objective>
Import external plan files into the GSD planning system with conflict detection against PROJECT.md decisions.

• --from: Import an external plan file, detect conflicts, write as GSD PLAN.md, validate via gsd-plan-checker.
• --from-gsd2: Reverse-migrate a GSD-2 project (.gsd/ directory) back to GSD v1 (.planning/) format. Runs gsd_run from-gsd2. Pass --path <dir> to migrate a project at a different path.

  </objective>

If `--from-gsd2` is in the `<arguments>` block:
Run the reverse-migration (append `--path <dir>` if provided):

Present the migration result to the user.
Stop here (do not run the standard import workflow).

Otherwise, execute the import workflow end-to-end. </process>
