Move brainstorm-server into skill directory per agentskills spec

Moves lib/brainstorm-server/ → skills/brainstorming/scripts/ so the brainstorming skill uses relative paths (scripts/start-server.sh) instead of ${CLAUDE_PLUGIN_ROOT}/lib/brainstorm-server/. This follows the agentskills.io specification for portable, cross-platform skills. Updates visual-companion.md references and test paths. All tests pass.
