Create Example Configuration Files

Create example configuration files for different use cases (personal projects, work, open source).

**Tasks:**
- [ ] Create `examples/` directory
- [ ] Create `examples/personal.yaml` for personal projects
- [ ] Create `examples/work.yaml` for work environment
- [ ] Create `examples/opensource.yaml` for OSS contributors
- [ ] Add detailed comments explaining each option
- [ ] Update README with examples

**Acceptance Criteria:**
- At least 3 example configs created
- Each config is well-documented with comments
- Examples cover different personas/use cases
- README links to example configs

Start by reading the README and identifying how configuration is currently described. Create the requested examples/personal.yaml, examples/work.yaml, and examples/opensource.yaml files with comments for each option, then update the README to link to all three and verify that each persona is represented.
