- Add getGlobalCasDir() to storage-root.ts - cmd-cas.ts uses global CAS dir, threadId kept for CLI compat - thread rm no longer deletes .cas/ directories - Rename createThreadCas → createCasStore (deprecated alias kept) - 134 tests passing BREAKING: CAS moves from <thread>.cas/ to <storageRoot>/cas/ Fixes #30
