Resolves the contradiction between CORE (wiki-first) and EXTENDED (which said
'use GrepAI first for any context lookup'). New order: wiki for known entities ->
GrepAI for code call-graphs / discovery / un-compiled detail -> raw reads. Keeps
GrepAI's irreplaceable code-search value; removes the redundant wiki overlap.
