collect_components() used dict.update(), which let conf.d silently
overwrite functions/ (or vice versa) when the same bare identity
appears in both, e.g. functions/auto-pull.fish and
conf.d/auto-pull.fish. The runtime guard can only ever look up the
bare status current-function/basename string, so both call sites
genuinely share one identity and their raw COMPONENT lines must be
concatenated, not replaced.
