Restructure repository: organize tools by purpose, create what search tool

- Move single-file tools to tools/ organized by category (security, forensics, data, etc.)
- Move multi-file projects to projects/ (go-tools, puzzlebox, timesketch, rust-tools)
- Move system scripts to scripts/ (proxy, display, setup, windows)
- Organize config files in config/ (shell, visidata, applications)
- Move experimental tools to archive/experimental
- Create 'what' fuzzy search tool with progressive enhancement (ollama->fzf->grep)
- Add initial metadata database for intelligent tool discovery
- Preserve git history using 'git mv' commands
