Subject: [PATCH] feat(console): accept 'direct' keyword in change_path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Setting a contact's path to Direct means 0 hops with an empty path body. The hex parser had no way to express that — empty/non-hex input always failed validation, and reset_path forces Flood instead.

Add a 'direct' keyword that bypasses hex parsing and sends an empty path with hash_size=1, producing out_path_len=0 (Direct). Update the usage block and the help entry to document it and to point at reset_path for the Flood case.
