Application regex lookbehind prevented older WebKit from loading the startup module graph. Replace lookbehind with boundary checks across run/terminal links, SQL aliases, debugger targets and refactoring; preserve Unicode boundaries, UTF-16 offsets and empty-match progress. Add compatibility and regression tests. Fixes #224 Refs #208
