feat(install): install the codebase-memory code graph with make install

The operator's three manual steps become part of the global install: install.sh runs yay -S --needed codebase-memory-mcp-bin when the binary is missing and yay exists, right before the existing auto_index switch; enable-plugins.js registers the DeusData/codebase-memory-mcp marketplace and enables codebase-memory@codebase-memory declaratively, the way it already handles caveman and ponytail, instead of claude plugin marketplace add and claude plugin install. kvb-agent-optimize now hands the operator make install instead of the single commands. test_dream checks the plugin and its marketplace.
