Add tools/gen_skin_template.py to generate a labeled 642x420 PNG template
for creating custom spritesheets. Move rg35xx device scripts from tools/
to device/rg35xx/. Point prev_sprite at its own cell (bottom-center) so
Prev and Next can have distinct icons.

Move device-specific content (hardware, software, libraries) from
TOOLCHAIN.md into new docs/rg35xx-plus.md. Add partition layout,
full boot chain trace (systemd → launcher.sh → loadapp.sh → dmenu_ln),
and sdlamp2 deployment instructions via dmenu_ln config toggle.

Replace Buildroot toolchain references with the new docker-arm64 setup
in CLAUDE.md, TOOLCHAIN.md, and the changelog.

The Docker/Buildroot toolchain produces 32-bit ARM binaries but the
RG35XX target runs a 64-bit aarch64 userland. Add docs/TOOLCHAIN.md
covering the full pipeline, config details, patches, and three possible
approaches to fix the architecture mismatch.

Single Makefile supports native builds (pkg-config) and cross-compilation
(CROSS_COMPILE/PREFIX env vars). Fixes -Wformat-truncation and
-Wstringop-truncation warnings at -O2 by sizing current_file to match
audio_files (256) and replacing strncpy with snprintf.

The spritesheet is compiled in as a C byte array. An external
controls.png in cwd still takes precedence for skinning. Includes
tools/embed_png.py to regenerate the header if the asset changes.
