Sticky Regex Literal Normalizer

Rewrite JavaScript source so that sticky regex literals become equivalent RegExp constructor calls, while non-sticky regex usage remains unchanged.

Capabilities

Rewrites sticky regex literals

• Converts a sticky regex literal like /abc/y into new RegExp("abc","y") while preserving the original pattern text. @test
• Keeps all flags when rewriting sticky literals (e.g., /foo/gy becomes new RegExp("foo","gy")). @test

Leaves other regex usage unchanged

• Keeps non-sticky regex literals exactly as written. @test
• Leaves existing RegExp constructor calls untouched, even when provided the y flag. @test
