Inconsistency between FuzzIntrospector API and YAML files

[MarkLee131]

Description

The function signatures returned by FuzzIntrospector's API differ from those in the YAML files provided by oss-fuzz-gen, causing issues when trying to use them together to extract API context information.

Example

1. bluez project - g_obex_new function

## conti-benchmark/comparison/bluez.yaml
return_type: "void"
signature: "GObex * g_obex_new(GIOChannel *, GObexTransportType, gssize, gssize)"

## FuzzIntrospector API response via query_fi_signature("bluez", "g_obex_new")
signature: "GObex *g_obex_new(GIOChannel *io, GObexTransportType transport_type, ...)"

Issues:

• return_type field is "void" but signature shows "GObex *"
• Parameter names missing in YAML but present in FI API

Reproduction

# Query FI API via locally deployed FI:
curl "http://localhost:8080/api/function-signature?project=bluez&function=g_obex_new"

# Compare with YAML
grep -A 5 "g_obex_new" conti-benchmark/comparison/bluez.yaml

My question is: will oss-fuzz-gen correct the format of yaml file? Or will this be solved from the FI part?
