fix: two fatal errors preventing plugin activation (v0.1.1)

1. NAMESPACE is a PHP reserved keyword — renamed to REST_NAMESPACE
   in the REST controller. This caused a parse error on activation.

2. Autoloader can't resolve PR_Core class — the class name equals the
   autoloader prefix exactly, so stripping "PR_Core_" yields an empty
   suffix and the wrong filename. Added explicit require_once in
   bootstrap, same pattern as PRAutoBlogger.
