Introduces hanzo-tools-* namespace packages for independent tool installation: Core packages: - hanzo-tools-core: BaseTool, ToolRegistry, PermissionManager - hanzo-tools-filesystem: read, write, edit, tree, find, search, ast (7 tools) - hanzo-tools-shell: dag, ps, zsh, shell, npx, uvx, open (7 tools) AI/Agent packages: - hanzo-tools-agent: critic, iching, review, network, CLI agents (12 tools) - hanzo-tools-memory: recall/create/update/delete memories, facts, KB (9 tools) - hanzo-tools-reasoning: think, critic (2 tools) Editor/Dev packages: - hanzo-tools-lsp: Language Server Protocol tool (1 tool) - hanzo-tools-refactor: rename, extract, inline, move, change_signature (1 tool) - hanzo-tools-database: SQL + graph database tools (8 tools) - hanzo-tools-editor: neovim integration (3 tools) - hanzo-tools-jupyter: notebook read/edit (1 tool) - hanzo-tools-browser: Playwright browser automation (1 tool) - hanzo-tools-todo: unified todo management (1 tool) Key improvements: - All subprocess.run calls have timeout protection - All tool .call() methods are async - Namespace package pattern for mix-and-match installation - Entry point discovery via hanzo.tools - No blocking imports (all < 2s) Also updates hanzo-mcp: - Browser tool integration - Tool install/registry for dynamic tool management - Auto-background timeout reduced to 60s
