When HERMES_UID remaps the hermes user from 10000 to another UID
(e.g. matching the host user's UID for bind-mount ergonomics), the TUI
launcher's esbuild step fails:
✘ [ERROR] Failed to write to output file:
open /opt/hermes/ui-tui/dist/entry.js: permission denied
TUI build failed.
This is because the Dockerfile's build-time `chown -R hermes:hermes` on
`/opt/hermes/{.venv,ui-tui,node_modules}` (line 154) wrote UID 10000,
and stage2-hook.sh only re-chowned `.venv` on UID remap — leaving the
TUI build trees still owned by the old UID.
Extend the stage2 re-chown to include the same set as the build-time
chown: `.venv`, `ui-tui`, `node_modules`. These are the runtime-writable
trees under $INSTALL_DIR; everything else under /opt/hermes is read-only
at runtime so keeping it root-owned is fine.
Original fix targeted docker/entrypoint.sh which is now a deprecated shim;
retargeted to docker/stage2-hook.sh where the .venv chown moved during
the s6-overlay rework.
