Resolves the default benchmark function for a project

This function attempts to auto-detect benchmark functions from the crate’s source. If no benchmarks are found, it falls back to a sensible default based on the crate name.

Arguments

• project_root - Root directory of the project
• crate_name - Name of the benchmark crate
• crate_dir - Optional explicit crate directory (if None, will search standard locations)

Returns

The default function name in format crate_name::function_name
