tsconfig paths not working when bundle mode is off

tsconfig paths imports remain untouched when I use ```bundle:false``` even used some esbuild plugin for tsconfig paths but still .Is it as known issue I am surprised no one has faced it yet.

No source file or test is identified. Reproduce the report with a TypeScript project using tsconfig paths and bundle:false, then inspect how tsup handles those imports when bundling is disabled. Done means the generated output resolves the configured paths, or the limitation is documented with a clear explanation.
