Review summary

This PR introduces fail-fast error handling (FailFast), a TypeAlias config, parameter-pack detection for templates, and consolidates ignore/type-lookup logic (getTypeObj, nsFeats, ignoreType). The renames (isConfTypeIgnored, getTypeObj) and the consolidated Type_Record/Typedef/Enum handling in toTypeEx are clear improvements.

One correctness bug stands out: ignoreType merges feats into a value copy that is never written back to the map, so re-ignoring an already-registered local type is a silent no-op. Remaining items are robustness and doc-accuracy nits. Details inline.
