- Implement CI workflow for formatting, linting, testing, and documentation checks. - Create publish workflow for automated publishing to crates.io. - Add .gitignore to exclude build artifacts and editor files. - Define Cargo.toml for corex and corex-core with dependencies and metadata. - Add README.md files for corex and corex-core with usage instructions and licensing. - Implement core execution primitives: spawn_io, compute, and spawn_bg with panic isolation. - Establish global engine context for resource management based on logical CPU cores. - Introduce error handling for compute panics.
