The CLASSIFICATION schema (docs/function-classification-schema.md) had
no path into config-help's lookup: no fish-config.index keyword, and
the only in-pipeline section (the C1 doc's "For function authors")
doesn't contain the word classification itself, so even the
normalized-heading-scan fallback missed it on that term. Two aliases
added, pointing at the existing section -- no heading renamed, matching
the index file's own stated purpose.
