Patch changes

• fd59b20 Default in-app frame classification now covers three gaps that left dependency and runtime frames marked as app code:

  • Cargo dependency sources are recognized by cargo's own on-disk layouts — registry/src/index.crates.io-<hash>/ and git/checkouts/<repo>-<hash>/<rev>/ — under any CARGO_HOME, not just ~/.cargo (e.g. /usr/local/cargo in the official Rust Docker images).
  • Crate-denylist matching strips trailing generic arguments first, so DWARF-derived names like poll_future<tokio::runtime::...> no longer feed a garbage segment (poll_future<tokio) into the crate check. Such names classify by their file path (fix above); when there is no file, they deliberately stay in-app — generic arguments are instantiation types, not the defining crate, and guessing from them would mislabel app functions generic over vendor types.
  • Fileless thread/process bootstrap symbols (__clone, start_thread, _start, the C main shim, and friends) are classified as not in-app. Other bare symbols — #[no_mangle] exports, C code linked into the binary — keep their previous in-app classification. — Thanks @​cat-ph!
