Subject: [PATCH] ci(antipattern): allowlist legit TS bridge/adapter paths

Broadens the TS exclusion list to cover all standard bridge/adapter conventions
(bindings/, tests/, test/, scripts/, mcp-adapter/, vscode/). Hard-stop on
plain TypeScript application code outside these paths is preserved.

Same change applied estate-wide; landed in stapeln as #24.
