Rename crate to mytheclipse and flatten workspace to single crate

- Rename corex -> mytheclipse (corex name taken on crates.io by an
  unrelated crate published by David-Kunz in 2023)
- Flatten corex + corex-core workspace into a single crate; all modules
  (context/error/io/compute/bg) now live directly under src/
- Update Cargo.toml metadata: real repo URL, docs.rs, author
- Update README, example, doc comments, tracing span names
- Fix CI: single package dry-run (corex-core no longer separate)
- Fix publish workflow: single cargo publish step

-- **`compute`**: enables `corex::compute`, panic-isolated execution on a sized Rayon pool.
-- **`bg`**: enables `corex::spawn_bg`, semaphore-bounded background tasks.
