On device, scanning failed (BT Inspector showed the scan as stopped and found
nothing). The firmware's GAP layer is initialised by the bt service, and ST's
stack disallows raw hci_le_set_scan_* / hci_le_create_connection in that state.
Switch the shared central layer to the GAP procedures: aci_gap_start_
observation_proc / aci_gap_terminate_gap_proc(GAP_OBSERVATION_PROC) for
scanning, and aci_gap_create_connection (+ terminate the direct-connection proc
to cancel) for connecting, with a short settle after stopping observation.
Also surface the raw BLE status code on BT Inspector's scan screen ("err 0xNN")
so any remaining failure is diagnosable on device. Needs the gap command group
exported (BLE_API default is all).

License Flipper Blue++ under GPL-3.0-or-later, matching the Flipper Zero
firmware it builds on and links against. Add the verbatim GPLv3 text as
LICENSE, an SPDX + copyright header to every original source file and
build.sh, and a License section to the README noting the app sources are
(C) 2026 Andy Dixon while the upstream firmware/SDK remain (C) Flipper
Devices Inc., both GPLv3. Headers are comment-only; the full suite still
builds and all faps link.

Point every app's fap_weburl at the renamed repo
(github.com/andydixon/flipper-bluepp) and recenter the build.sh header on the
full-stack BLE firmware and the app suite rather than a single app. GitHub
repo renamed from flipper-bt-inspector; the slug drops "++" since GitHub repo
names cannot contain "+".
Extract the reusable BLE central/GATT client and name/value decoders into
libble/ (moved out of bt_inspector). build.sh now stages libble/*.{c,h}
into each app dir at build time and builds every app in APPS=(...).
New app ble_hid_host: connects to a BLE keyboard or mouse, discovers the
HID service (0x1812), sets protocol mode (boot when offered, else report),
subscribes to the input-report characteristics, and decodes keyboard
(modifiers + key names) and mouse (buttons + dx/dy/wheel) reports live.
Events scroll on screen and are logged with raw bytes to
apps_data/ble_hid_host/. No pairing, so encryption-gated keyboards stay
silent; open devices and most mice work. Both faps build and pass APPCHK.
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.
Built-in firmware app (needs the full ST BLE stack) with live RSSI-sorted
scan list, advertisement decoding (Apple Continuity, Microsoft CDP, Fast
Pair, Eddystone), connect/discover/read/write/notify, device-info summary,
value history and a timestamped session log. build.sh produces a firmware
update package with COPRO_STACK_TYPE=ble_full and the app compiled in.
