feat(CH32): expose safe graph removal flags in remove CLI command

- Add --hard flag for physical removal (supersedes soft delete)
- Add --recursive flag to allow subsystem removal
- Add --repair flag to repair must_follow chains after hard delete

Exposes removeNodeOp() safety features through CLI interface.
All 458 tests pass. Updates CH32 status to complete.
