Rodin 9e15b73a23 revert: remove YAML support, keep JSON-only

The external dependency (goccy/go-yaml) violates the repository's
stdlib-only convention (CONVENTIONS.md). While YAML provides better
readability for multi-line strings, the convenience doesn't justify
breaking a hard rule.

Reverts:
- External dependency on github.com/goccy/go-yaml
- YAML parsing logic in persona.go
- YAML persona files (restored as JSON)
- YAML-specific tests
- Design document (feature rejected)

The persona files work fine with JSON. Multi-line strings use \n escapes
which is less pretty but acceptable for internal files.

This addresses all MAJOR findings from review bots regarding the external
dependency violation.

Rodin 006b7a3b27 feat: add YAML support for persona files (#57)

- Add github.com/goccy/go-yaml dependency (v1.19.2)
- Update parsePersona to detect format by file extension
- Support both .yaml and .yml extensions (case-insensitive)
- Convert built-in personas to YAML format
- Add comprehensive tests for YAML parsing
- Update README with YAML examples and documentation

YAML provides cleaner multi-line strings via literal block scalars
and supports comments, making persona definitions more readable.
JSON remains supported for backwards compatibility.

Closes #57

## Language & Dependencies
- Go standard library only — no external dependencies.
- Target the latest stable Go release.
- **STRICT ALLOWLIST:** Only packages listed below may be imported. No exceptions.
### Approved Third-Party Packages
| Package | Use Case | Scope |
|---------|----------|-------|
| `gopkg.in/yaml.v3` | YAML parsing (persona files, config) | production |
| `github.com/google/go-cmp` | Test comparisons (`cmp.Diff`) | test only |
**Any import not in this table or the Go standard library is forbidden.**
Only *direct* dependencies (listed in go.mod without `// indirect`) are checked against this allowlist. Transitive dependencies pulled in by approved packages are implicitly allowed.
To request a new dependency:
1. Open a PR that ONLY updates this table
2. Requires explicit approval from Aaron
3. After merge, a separate PR may use the package
*Enforcement: `scripts/check-deps.sh` parses this table — update only here.*

YAML is the recommended format for personas because it supports:
- Multi-line strings with `|` blocks (cleaner identity definitions)
- Comments for documentation
- More readable arrays and nested structures
JSON is also supported for backwards compatibility—just use `.json` extension.
