🤖 Augment PR Summary

Summary: This PR clarifies the project's interpretation of ECMA-262 regex syntax for JSON Schema.

Changes:

Documents that validation accepts the Unicode-aware u and v readings.
Explains why the legacy, Annex B-enabled no-flag reading is intentionally excluded.
Links the rationale to the relevant ECMA-262 sections and JSON Schema's Unicode guidance.
Describes practical strict-mode consequences for syntax characters, escapes, and properties.
Documents parser nesting and downstream compilation limitations.
Extends the API examples with Annex B-sensitive invalid patterns.
Adds broad regression coverage for legacy escapes, malformed braces, class ranges, lookaheads, and set notation.
Adds Unicode, astral-character, and parser-depth boundary cases.

Technical Notes: The tests codify strict Unicode parsing rather than a browser's legacy no-flag behavior.
