Add missing repository components for complete supercharge.sh installation

Added all directories and files expected by supercharge.sh:

- hooks/ (5 hook scripts for session management and AI consultation)
- commands/ (3 custom slash commands: brainstorm, write-plan, execute-plan)
- plugins/ (plugin references for glm-plan, rust-analyzer, marketplaces)
- bin/ralphloop (Ralph Orchestrator wrapper for autonomous iteration)
- scripts/sync-agents.sh (agent synchronization script)
- templates/ (config templates: settings, hooks, config.json)

This completes the repository structure so supercharge.sh can install
all components without warnings.
