PARSE and PARSE-NAME were using the deferred pending mechanism which
broke when called from compiled code (the calling word continued
executing before PARSE ran). Replaced with inline host functions that
read >IN/#TIB directly from WASM memory and parse immediately.
This fixes utilities.fth $"/$2" failures that left stack residue
cascading into all subsequent compliance test suites.
Also: core_ext 17→14, string 27→17.
