Move libpanto projects to libpantograph dependencyHEADmain

Remove the in-repo libpanto sources and binding projects from pantograph.
Consume libpantograph through the Zig package URL at
code.tjp.lol/libpantograph.git, including the Lua module artifact used by
CLI extensions.

-#!/usr/bin/env lua
--- A tiny standalone libpanto-lua app: one prompt in, streamed text out.
---
--- Run with Lua 5.4 after building/installing libpanto-lua, for example:
---   LUA_CPATH='./libpanto-lua/zig-out/lib/?.so;;' lua examples/simple-agent.lua "list the files"
---
--- Required environment:
---   PANTO_API_STYLE=openai_chat|anthropic_messages
---   PANTO_API_KEY=...
---   PANTO_BASE_URL=...
---   PANTO_MODEL=...
