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.
