docs: update coverage, READMEs, and add security tests

Browse Source 
- Update COVERAGE.md to reflect completed features (now ~60%)
- Update main README with features and tools list
- Update CLI README with streaming options
- Expand API tests from 5 to 11 (add stream endpoint tests)
- Add 14 security tests for path traversal, command injection
- Total tests: 109 (up from 88)

| Separate CLI package | `cli/` at root | Can be extracted as standalone client |
| Monorepo structure | `webber-api/`, `webber-cli/` | Separate packages, shared root |
| Sanitized Ollama provider | Custom wrapper | Fixes PydanticAI + Ollama `content: null` bug |
