Method find_from_env

crates/memtrack/src/allocators/mod.rs:84–109

Discover allocators from binaries listed in the `CODSPEED_MEMTRACK_BINARIES` env var. The variable is a platform path-list. Each path is checked for a statically linked allocator via [`AllocatorLib::from_path_static`]. Invalid or missing paths are silently skipped (with a debug log).
