Add comprehensive operator integration tests for REMESH
Verify all 13 canonical operators integrate correctly with REMESH: - Hierarchical mode: IL, VAL, SHA, NUL - Rhizomatic mode: OZ, UM, THOL - Fractal Harmonic mode: RA, NAV, AL, EN - Indirect: ZHIR (post-recursion with grammar validation) - Grammar compliance: U1-U4 rule validation - Structural similarity verification 17 integration tests covering all operator relationships All tests pass, confirming proper integration Co-authored-by: fermga <203334638+fermga@users.noreply.github.com>
