Problem

PR #330 added package name disambiguation for Go benchmarks with duplicate names across packages. However, some users (e.g., gofiber/fiber) already applied workarounds by manually including the package name in their benchmark names.

With the current implementation, these workarounds would result in duplicate package names:

• BenchmarkFoo_middleware_cache → BenchmarkFoo_middleware_cache (github.com/gofiber/fiber/v3/middleware/cache)

Proposed Solution

Before adding the package suffix, check if the benchmark name already contains a reference to the package (full path, normalized path, or partial suffix).

Known Workaround Pattern (gofiber/fiber)

# Strip module prefix, replace / with _, append with _
BenchmarkAppendMsgitem → BenchmarkAppendMsgitem_middleware_cache
