[Feature request] Can we have a global ignore list for single word AZC analyzer similar to customwords.txt

This could help reducing the amount of manual work needed for each RP and make process more automated.

The issue does not name any files, tests, or entry points. Start by locating the single-word AZC analyzer and customwords.txt handling, then clarify the global ignore-list format, scope, and expected behavior before implementation; done means the analyzer consistently honors the shared list.
