refactor: use .opencode/opencoder/ directory structure

Move all opencoder files under .opencode/opencoder/ to keep all
OpenCode-related files together in a shared parent directory.

Changes:
- .opencoder/ → .opencode/opencoder/
- opencoder.json → .opencode/opencoder/config.json
- Updated fs.ts paths, config.ts loader, CLI help text
- Updated .gitignore to ignore state/logs but allow config
- Updated README.md and AGENTS.md documentation
- Renamed opencoder.json.example → config.json.example
