EXT-32: hard per-server cap on injected MCP instruction length.

A connected MCP server could advertise a very long instructions string that would then ride along in EVERY turn’s system prompt and bloat context. This is a simple defensive constant (no config-schema plumbing — that stays out of this node): text beyond the cap is dropped and a truncation marker is appended so the model knows it was clipped. Generous enough that realistic server instructions pass through untouched.
