chore: rename corex-* crates to mytheclipse-* namespace

Rename all `corex-cache`, `corex-storage`, `corex-event`, `corex-config`,
and `corex-crypto` crates to `mytheclipse-cache`, `mytheclipse-storage`,
`mytheclipse-event`, `mytheclipse-config`, and `mytheclipse-crypto`
respectively, aligning with the `mytheclipse` root crate naming convention.

- Convert root `Cargo.toml` from a package manifest to a workspace
  manifest with explicit member paths
- Update crate names in each `Cargo.toml` and docs.rs URLs
- Update all import paths, module doc comments, and error/panic messages
  from `corex-*` to `mytheclipse-*` across source and README files
- Update CI workflow and publish script to reference the new crate names<tool_call></think>chore: rename corex-* crates to mytheclipse-* namespace
