Update project configuration and dependencies for OmniScript

## Summary
- Added a new `.env.example` file to provide environment variable examples for development.
- Updated `package-lock.json` and `pnpm-lock.yaml` to reflect new dependencies and versions, including the addition of `omniscript-parser` and updates to ESLint and TypeScript packages.
- Refactored `cli/package.json` to rename the CLI tool from `@osf/cli` to `omniscript-cli` and updated its version to `0.5.1`.
- Changed import statements in `cli/src/osf.ts` to use the new `omniscript-parser` package instead of the previous path.
- Updated `parser/package.json` to rename the parser package from `@osf/parser` to `omniscript-parser`.

## Testing
- Run `pnpm test` to ensure all new and existing tests pass successfully.
