Cut the dev3 skill's token footprint: the Claude SKILL.md no longer duplicates the protocol already injected into the system prompt (a PROTOCOL.md fallback covers sessions started outside the launcher), the skill invoke now uses `dev3 current --brief` instead of re-printing the full help and task description, and the shared skill body was rewritten ~40% denser for all agents. A Claude session now carries ~4k tokens of dev3 protocol instead of ~13.5k.
