Epic: v0.1.0 — Foundation (MVP)

[alvinreal]

Goal

Get the core pipeline working: read a file in one format, convert through Universal Value, write in another format. No mappings yet — just straight conversion.

Success Criteria

• morph -i data.json -o data.yaml works correctly
• JSON, YAML, TOML, CSV readers and writers
• Format auto-detection by file extension
• Pipe-friendly (stdin/stdout)
• Pretty and compact output modes
• Comprehensive test suite for all format conversions

Sub-Issues

Track individual issues labeled v0.1.0

TDD Approach

Every component starts with tests:

1. Write failing tests for the Universal Value type
2. Write failing tests for each format (round-trip: parse → UV → serialize → parse → compare)
3. Write integration tests for CLI end-to-end
4. Implement until green
