Subject: [PATCH] Fix craft dispatch: add turtle attach/detach handlers,
 re-scan on craft, log failures

- Add peripheral_attach handler to auto-detect crafting turtle connecting after boot
- Update peripheral_detach handler to clear craftTurtleName when turtle disconnects
- Re-scan peripherals for turtle in display.lua craft handler if none known
- Add log.warn when craft turtle check fails (was silent notification only)
- Sync ctx.craftTurtleOk from broadcastState so display.lua has current value
