The identification agent attributed probo_distinct_id to Mixpanel
purely on the shared distinct_id token, and the enrichment agent
returned no description for the glob ph_phc_*_posthog because it
searched the literal "*" string and found nothing.
Tighten the identification prompt so attribution requires a perfect
pattern match or a meaningful prefix that belongs to the vendor; a
generic token behind a different prefix is not a match. Teach the
enrichment prompt to strip wildcard and variable parts before
searching, and to treat a vendor name embedded in the key as
corroboration so clearly-named trackers still get a description.
