Initial gitsyncer implementation with version support

- Initialize Go module for github.com/paul/gitsyncer
- Add version package with version info (v0.1.0)
- Implement main.go with --version flag support
- Create comprehensive Taskfile.yaml for build automation
- Add CLAUDE.md with project documentation

The binary can be built with 'task' or 'go build -o gitsyncer ./cmd/gitsyncer'
