libchat's hand-written FFI to liblogosdelivery is replaced by the upstream
`waku-bindings` crate. It is unpublished and its build script compiles the
native library from Nim sources in its own submodule, so it is consumed from
a checkout under vendor/ as its README prescribes, pinned as a submodule.
The macOS link frameworks and the chronicles log-level define ride in this
crate's .cargo/config.toml: a path dependency's config is not inherited, and
the native node's logging is compile-time only (its runtime logLevel is a
no-op), so without the define the library floods stdout and no TUI on top is
readable. The vendor directory is excluded from the workspace so its Nim
build is not dragged into `--workspace` builds, fmt or clippy.
