🤖 Augment PR Summary

Summary: This PR removes redundant CLI tests and strengthens tests that previously asserted little beyond exit status.

Changes:

• Removes duplicate TypeScript codegen and verbose test-description coverage.
• Renames CI HTTP failures to distinguish non-JSON responses from valid JSON that is not a schema.
• Validates that a bundled document is formatted, parseable JSON after extracting its output.
• Exercises compiled patternProperties with matching valid and invalid instance properties, including JSON diagnostics.
• Makes dialect-option precedence observable through a Draft 6 const schema.
• Verifies failed lint fixes do not modify individual schemas or any files in a directory.
• Expands lint fixtures so top-level scope and built-in-rule interactions are observable.

Technical Notes: The changes primarily improve regression-test signal without modifying production behavior.
