feat: initial monorepo with vika-sdk and vika-cli

- vika-sdk: HTTP client, types, records/fields/views/spaces/nodes API
- vika-cli: clap CLI for AI agents, JSON output, --compact flag
- 37 tests: 14 unit (sdk) + 10 unit (cli) + 13 mock integration (no API key needed)
- GitHub Actions: CI on ubuntu/macos/windows, release with cross-platform binaries + crates.io publish
