chore: open-source readiness — LICENSE, CONTRIBUTING, templates, package metadata

- Add MIT LICENSE
- Add CONTRIBUTING.md with setup, conventions, PR workflow
- Add GitHub issue/PR templates
- Add repository/homepage/bugs/license to all package.json files
- Add Install section to README before Quick Start

 Agents are pluggable CLI binaries (`uwf-hermes`, `uwf-builtin`, `uwf-claude-code`, or custom commands). The engine spawns the configured agent with `<thread-id>` and `<role>`, sets `UWF_EDGE_PROMPT` from the graph transition, and captures both the agent's markdown output and a detail CAS node for session replay.
 
+## Install
+
+```bash
+npm install -g @uncaged/cli-workflow
+```
+
+Requires [Bun](https://bun.sh/) runtime (used internally for TypeScript execution).
+
+## Quick Start
+
+```bash
+# 1. Configure provider, model, and default agent
+uwf setup
+
+# 2. Register a workflow from YAML
+uwf workflow add examples/solve-issue.yaml
+
+# 3. Start a thread (creates head pointer; does not execute)
+uwf thread start solve-issue -p "Fix the login redirect bug"
+
+# 4. Execute steps (one at a time, until done)
+uwf thread exec <thread-id>
+```
+
+Use `-c, --count <number>` on `thread exec` to run multiple steps in one invocation. Override the agent with `--agent <cmd>`.
