Sticky Regex Build Support

Enable compilation of JavaScript sources so sticky regex literals work in runtimes without native y flag support by configuring the build with a sticky-regex Babel transform.

Capabilities

Rewrites sticky regex literals

• Compiling code containing a sticky regex literal such as /foo/y emits output where that literal becomes an equivalent RegExp constructor call that preserves the y flag and any other flags present (e.g., /foo/gy becomes new RegExp("foo", "gy")). @test

Leaves non-sticky regex untouched

• Compiling code containing regex literals without the y flag returns output that keeps those literals unchanged (e.g., /foo/gi remains /foo/gi). @test

Babel config enables sticky transform

• The build setup exposes a babel.config.json (or equivalent) that lists the sticky regex transform plugin so consumers can enable it via config, and compilation uses that config entry when transforming sources. @test
