Replace the tsc + babel pipeline with a single esbuild invocation that produces a self-contained dist/entry.js. The nix TUI derivation no longer copies node_modules — only dist/ + package.json ship, shrinking the output from hundreds of MB to ~2.9 MB. - ui-tui/scripts/build.mjs: new esbuild bundler. Aliases @hermes/ink to source (esbuild's __esm helper doesn't await nested async init, which breaks lazy-assigned exports like 'render' when re-exporting through a prebuilt submodule). Stubs react-devtools-core (dev-only). Injects a createRequire shim for transitive CJS deps. Strips the shebang from src/entry.tsx because Nix patchShebangs mangles '/usr/bin/env -S node --max-old-space-size=8192 --expose-gc' — it drops the 'node' token. The Python launcher always invokes node explicitly, so the shebang is redundant. - nix/tui.nix: installPhase no longer copies node_modules or the @hermes/ink packages dir. - nix/checks.nix: drop the 'node_modules present' assertion. - hermes_cli/main.py: _tui_need_npm_install short-circuits when dist/entry.js exists and no package-lock.json is present. That is the prebuilt-bundle layout (nix / packaged release) and there is nothing to install. Without this, the launcher tried to npm install in a non-existent site-packages/ui-tui path.
