feat(eltex): add ai-eltex launcher for corporate LLM proxy

ai-eltex runs Claude Code through the Eltex LiteLLM proxy
(http://llm.eltex.loc:4000, team GLM subscription). The personal key
from admins is checked via /v1/models and stored in
~/.config/ai-setup/eltex_key; the model is taken from the key's
allowed list (ELTEX_MODEL / ELTEX_BASE_URL override). The proxy
ignores effort/thinking, so no effort forcing. /logout-eltex and
/logout in ai-eltex drop the key; setup.sh status shows it.

ru-bypass: hosts block now has an end marker and only that block is
rewritten, manual entries outside it survive; llm.eltex.loc/llm2 added
since the VPN DNS does not resolve it.
