Replaces the vendored 11-file LXMF subtree under
lib/microreticulum-shim/LXMF/ with a symlink at lib/microLXMF
pointing at ~/repos/microLXMF. PlatformIO's lib_ldf_mode = deep+
follows the symlink, finds microLXMF/library.json, and treats it as
a regular library — no platformio.ini changes required.
Build verified: pio run -e tdeck succeeds, RAM 21.4%, Flash 71.3%
(comparable to pre-extract baseline).
The lib/microreticulum-shim/ "fork-only-glue" library remains in
place — it still owns BZ2 + libbz2 + Display + FileSystem +
Instrumentation + Utilities pieces that haven't been extracted.
For collaborators without ~/repos/microLXMF checked out, the
symlink will dangle. Once microLXMF has a tagged release we'll
swap the symlink for a `lib_deps` git URL pin.
