The host-side build/verify/inspect/serve CLI now lives as a standalone Rust
project at https://github.com/vk496/motatool. Remove the in-tree C++ copy
(tools/motatool/) and repoint the docs (ota_protocol.md, ota_user_guide.md,
tools/mota/README.md) at the standalone repo.
No cross-dependency either direction: MeshCore's firmware build never invoked
motatool (only tools/mota/ Python glue runs in the build), and motatool depends
only on the shared .mota wire spec in docs/ota_protocol.md. tools/mota/
(pio_endf.py EndF hook, motalib.py reference lib, gen_targets.py) is unchanged.
The EndF post-build stamper read the version via _cppdef('FIRMWARE_VERSION'), which only sees -D build flags — but MeshCore authors FIRMWARE_VERSION as a header #define in each example, so the stamper found nothing and defaulted fw_version to 0. Every .mota / OTA advert then reported v0.0.0 while `ver` (which reads the header at runtime) showed the real version.
Read the header value as a fallback WITHOUT moving where MeshCore authors it: honor a -D override first (the header's #ifndef guard invites it, for release builds), else read the #define from the example this env builds (via build_src_filter), falling back to the repo-wide value when unambiguous. Purely additive to our own EndF tooling — no MeshCore source changed.
HW-verified: RAK4631 now reports `fw v1.17.0` in ota stats/ls (was v0.0.0), matching `ver`.
