oxmc f6176009b1 Add recovery_ui and recovery_toolkit scaffolding (first draft, not build-tested)
Stages TWRP's GUI engine and standalone tooling as PawletOS-owned modules
instead of a bootable/recovery fork, per the plugin-architecture finding in
NOTES-ota-recovery-ab.md: stock recovery_main.cpp already dlopen()s
librecovery_ui_ext.so and dlsym()s make_device() from it at runtime, so the
UI layer doesn't require touching stock bootable/recovery at all. Confirmed
via source grep that recovery.cpp/install.cpp have zero references into the
partition manager/backup engine/GUI code and vice versa.

recovery_ui/: TWRP's gui/, minuitwrp/, libpixelflinger/ (copied verbatim,
GPL-3.0), plus a new device/ providing PawletTwrpUI (a ScreenRecoveryUI
subclass) and make_device() — written from scratch against stock's
RecoveryUI/ScreenRecoveryUI virtual-method contract, since TWRP's own fork
never ships a make_device() (every real TWRP device provides its own, and
no reference device tree was available to copy from). Top-level Android.bp
defines librecovery_ui_pawlet_twrp, the module TARGET_RECOVERY_UI_LIB should
point at. gui/Android.bp and minuitwrp/Android.bp had their include_dirs
rewritten for the new paths.

recovery_toolkit/: partition manager, backup engine (tar/digest/adbbu/apex),
filesystem/format support (exfat/dosfstools/gpt/fuse/mtp/crypto), scripting
(openrecoveryscript/orscmd/twrpinstall), shared helpers. Source only, no
Android.bp yet for any of it.

Known gap blocking recovery_ui from actually linking: gui/'s libguitwrp
depends on libaosprecovery, built from recovery_toolkit/helpers/twrp.cpp via
a Go Soong plugin (libaosprecovery_defaults.go) not yet ported. Neither repo
has been build-tested — no local AOSP build environment available in this
workspace. See each directory's README.md for a precise done/not-done
breakdown.
