fix(action/tsconfig): noEmit + exclude dist to silence editor TS5055

action/tsconfig.json had "exclude": [] (overriding the default outDir
exclusion) and unset noEmit, so tsserver pulled action/dist/**/*.d.ts
into the program and flagged 92 TS5055 errors ("Cannot write file ...
.d.ts because it would overwrite input file") any time dist/ existed.
the CLI typecheck script passes --noEmit so it never tripped — only the
editor was affected.

emit is owned by tsconfig.exports.json, which extends this one and
overrides noEmit: false, emitDeclarationOnly: true. so the main config
is editor/typecheck only and should declare noEmit: true.
