First phase of the OSS / pro split. Goal: open the seams so the auth/DB/admin
stack can move into the private overlay (Phase 2-3) without the routes that
stay in OSS (compile, libraries, simulation, iot_gateway) having to know.
Backend
-------
* New app/core/hooks.py — registry for record_compile, get_current_user_id,
and lifespan startup tasks. Each hook is a no-op by default; overlays
call register_* in register_pro(app) to plug in a real implementation.
* compile.py now imports only from app.core.hooks. Drops the direct deps on
app.core.dependencies, app.database.session, app.models.user, and
app.services.metrics. Route signatures use `Depends(get_current_user_id)`
instead of `Depends(get_current_user)`; the metric helper passes user_id
through rather than a User instance.
* compile_chip.py drops the unused _current_user Depends entirely.
* main.py wraps the auth/DB stack import in try/except. When it succeeds
(today's behavior on velxio.dev), an adapter bridges record_compile and
get_current_user_id to the existing app.services.metrics + dependencies,
and the create_all + ALTER TABLE migration block runs via a registered
lifespan_startup hook. When it fails (the post-Phase-2 OSS image), main
logs "running stateless" and skips registering anything — the routes
still load and behave as no-ops for metrics + always-anonymous for auth.
Frontend
--------
* useAutoSaveProject becomes a skeleton: one useState + one useEffect that
delegates to an installed AutoSaveImpl. installAutoSaveImpl() replaces
the impl without changing hook count, so React's rules-of-hooks stay
satisfied even after the impl moves out of OSS.
* New hooks/autoSaveImpl.ts holds the original logic (debouncing, dirty
detection, owner eligibility, fetch keepalive on unload), refactored to
emit() instead of useState. It self-registers at module load; main.tsx
imports it for the side effect.
* AppHeader wraps the entire user-vs-login UI in a data-velxio-slot
="header-auth" boundary. Today the OSS UI still renders inside the slot
— the overlay can portal-inject additional items now, and in Phase 3
the slot becomes the sole owner of header auth UX.
Behavior is identical on velxio.dev (pro overlay imports everything
successfully, every adapter wires up). The change is purely structural:
deleting the auth/DB modules tomorrow no longer crashes OSS at import.

- Implemented `esp32_spi_chip_demo.ino` to demonstrate SPI communication with a 74HC595 shift register.
- Created `esp32_uart_chip_demo.ino` for UART loopback testing with ROT13 transformation.
- Added Python tests for compiling chips and sketches, ensuring valid WASM output and successful compilation for various board families.
- Developed end-to-end tests for ESP32 with custom chips using I2C and SPI, validating synchronous communication through the backend.
- Introduced GPIO bridge tests to verify serial communication and GPIO state changes.
- Ensured all tests validate the expected behavior of the custom chips and their interaction with the ESP32 firmware.
