docs: render llms.txt at build time from a Jinja template

Replace the static curated llms.txt with a build-time render that
interpolates html_baseurl and release into the file, so the file always
matches the branch it was built from. llms-full.txt is already
auto-generated by sphinx-llms-txt.

-# VyOS
-
-> VyOS is a free, open-source network operating system based on Debian GNU/Linux.
-> It provides routing, firewall, and VPN functionality via a unified CLI using
-> `set`/`delete`/`show` command hierarchy. Current rolling release is 1.5.x (circinus).
-
-VyOS configuration follows a tree structure. All configuration commands start with
-`set` (to add/change) or `delete` (to remove). Changes are staged and applied with
-`commit`. The CLI hierarchy maps directly to the documentation structure.
