esbuild inlines __dirname and __filename as static strings when converting
ESM TypeScript source to CJS format. These build-time paths shadow the
runtime's native __dirname (provided by Bun/Node CJS module wrapper),
breaking path resolution for viewer UI, mode loading, and database
initialization on end-user machines.
Add a post-build step that removes the hardcoded var declarations from
all bundled CJS outputs, allowing the runtime globals to work correctly.
