Scopes the first of F's four pieces to .mcp.json relocation + Chromium profile seeding only. Drops Shipyard's permission/auto-approval writes (no existing CCAM pattern for a backend command granting permissions, and the rules named agents not in scope: pr-reviewer has no driving skill to port, ticketer is a later task) and the node-version wrapper (environment-specific workaround, no evidence this repo needs it).
