Jaehyun Kim 5fd751e8d7 Revert diff_files/diff_files_sorted to original return behavior 
Revert error-on-mismatch back to return 1, as the new GitHub Action
(github-actions-are-differences-found) now detects "Differences found"
in CI output, making the error approach unnecessary.

Jaehyun Kim cf1db116dc Remove dead re-add constraint blocks from SDC tests 
removeConstraints was removed upstream in STA 3.0 (MCMM refactor).
The "Re-add constraints" blocks were originally preceded by
remove_constraints calls; without them, the re-adds are no-ops.

Jaehyun Kim 616cb6234a Fix report_checks -fields {nets} typo to {net} across test scripts 
The valid field name is "net" (singular) per search/Search.tcl.
Using "nets" triggered Warning 168 (unknown field) silently in
29 test scripts. Fix the field name and regolden .ok files.

Jaehyun Kim b30c82b2d0 Make diff_files/diff_files_sorted error on mismatch 
Previously these functions returned 1 on mismatch but no caller
checked the return value, allowing roundtrip failures to go
undetected. Now they call error() so the sta process exits
non-zero and the regression runner catches the failure.

The remove_constraints API was permanently removed from Sta.
Delete the commented-out calls, TODO comments, and "skipped"
print statements instead of keeping placeholder blocks.
