Unify minimum/maximum error handlers with draft-04 compatibility

[Padmashree06]

Description

This PR introduces unified error handlers for:

• minimum, exclusiveMinimum and draft-04 minimum
• maximum, exclusiveMaximum and draft-04 maximum

The handlers now select and report only the most restrictive constraint, producing a single validation error instead of multiple overlapping messages.

Additional Updates

• Added normalization for the combined handlers
• Included test cases.
• Existing individual handlers are commented out in index.js to avoid overlap and can be removed if preferred.

Tests

All tests pass locally.

Fixes

Issue: #135

The new error handlers look like the right idea, but there's a lot of cleanup that needs to be done everywhere else.

• You need to rebase your branch and resolve conflicts
• The old handlers need to be removed
• There's no need for new normalization handlers
• There should be no changes to hyperjump-json-schema.test.js

Thank you for the feedback.
I will do the necessary changes.

Regarding the changes to hyperjump-json-schema.test.js, I made those adjustments because I was running into some reference errors during testing. I’m sorry if modifying that file wasn’t the right approach. I’ll revert those changes and look into fixing the underlying issue properly instead.
