v0.11.0 — Safe optional tool setup

• Changed the optional dependency policy from "document only" to "attempt safe setup during install, then fail open": Graphify, Claude Video/media helpers, and Design Extract browser support now get non-privileged installer attempts unless --no-tool-install is set.
• Added installer support for graphifyy==0.1.14 through pipx or a managed user-space virtualenv, never global pip, sudo, or --break-system-packages.
• Added safe helper setup paths for yt-dlp, ffmpeg, and Design Extract browser support while preserving runtime preflights, manual fallback commands, and no API-key collection.
• Updated Graphify router/instruction guidance to prefer an existing project graph for codebase relationship questions, recommend Graphify's own watch/git-hook freshness flow when stale, and avoid any AgenticSupercharge background graph daemon.
• Strengthened global objectivity guidance against sycophancy and weak-premise feedback loops, including proactive challenge for consequential, ambiguous, or irreversible decisions.
• Updated docs, third-party notices, readiness checks, router catalog, and consistency tests for the v0.11 plug-and-play dependency policy.
