Clippy lints don't show up in nested crates

rust-analyzer version:
tested on rust-analyzer 1.92.0 (ded5c06 2025-12-08) and rust-analyzer 0.3.2753-standalone

rustc version:
rustc 1.92.0 (ded5c06cf 2025-12-08)

editor or extension:
Helix (Arch Linux; tested both extra/helix and aur/helix-git)

relevant settings:
in ~/.config/helix/languages.toml:

[language-server.rust-analyzer.config]
check.command = "clippy"

steps to reproduce:
Set up crates:

$ cargo new meow
$ cd meow
$ cargo new --lib woof
$ cd woof

Edit (woof/)src/lib.rs to trigger a clippy lint. For example, inserting the line let _ = 'a'..'z'; into the example function causes a lint with default clippy settings.

expected behavior:
The clippy lint should show up in the editor, as it does in non-nested crates (e.g. meow in the example)

actual behavior:
No clippy lints show up in the editor

Reproduce the issue with the nested woof crate, Helix, and check.command = "clippy" in languages.toml; use src/lib.rs to trigger the example lint. Compare diagnostics for the nested crate with the working top-level meow crate, and consider the issue done when the clippy lint appears in the editor for woof as well.
