Make Vilix automatic. Call this when the user asks "how do I make
this automatic", "set this up so it remembers on its own", or right
after a first connection when offering setup.
Returns a short custom-instructions block the user pastes into THIS
tool's personalization / custom-instructions settings so the AI starts
calling Vilix (get_context / save_turn) on its own — plus exactly where
to paste it. `recommended` is the block matched to the caller's tool;
`blocks` lists every supported tool's block (and for headless always-on
tools, an enforce-every-turn variant for an always-on rules file).
`source` (optional) — the tool label you run in (e.g. "ChatGPT",
"Claude", "Cursor", "Codex", "Copilot", "Windsurf"), used to pick the
right block; omit to get the generic default. This is an OPT-IN setup
you hand to the user — it is not auto-applied;
Vilix logs nothing silently.
