Refactor storage access control to use dynamic public prefixes
sourced from `getAllStoragePublicPrefixes()` instead of a hardcoded
`blog` check. Each module can now declare its own public storage
prefixes via `defineModule()` storagePublicPrefixes, making the
system extensible without modifying the core handler.
Also adds a `posts` path handler requiring admin access for private
post types, removes the deprecated `version` API endpoint and its
rate-limit exemption, and minor whitespace/comment cleanup.
Update all references across source files, documentation, and
configuration to reflect the new package scope and name. This includes
updating `.npmrc` registry config, install instructions, module
examples, and all import path comments throughout the codebase.
