build.sh now adds ST's aci_*/hci_* headers to the SDK (with extern "C"
guards, the API table is C++), lets fbt regenerate api_symbols.csv and
enables the selected functions (BLE_API=hci,gatt default; min; all).
The app builds as a normal .fap shipped inside the update package and
loadable from SD, saving ~12 KB of firmware flash versus the built-in
(min mode: ~22 KB). qsort replaced with an insertion sort since libc's
qsort is not exported to apps. README documents modes and flash budget.
