Updating crates.io index after every `cargo clean`

rust-analyzer version: rust-analyzer 0.3.2509-standalone
(also reproduced in later versions, including nightly)

rustc version: rustc 1.88.0 (6b00bc388 2025-06-23), rustc 1.87.0 (17067e9ac 2025-05-09)

editor or extension: neovim v0.11.2, default rust analyzer settings

code snippet to reproduce:

# Create new project
cargo init sample
cd sample

# run editor
nvim src/main.rs

Rust analyzer starts to show status "updating crates.io index". After sometime message "cargo metadata: ?" also appears. It blocks if there is no connection to the Internet.

On the other hand I can simply run cargo clean && cargo metadata without connection to the Internet.

Also I tried to set rust-analyzer.cargo.noDeps: true and rust-analyzer.cargo.autoreload: true, this does not solve the problem.

Reproduce the behavior with the listed cargo init, nvim, cargo clean, and cargo metadata commands, including without an Internet connection. Trace the rust-analyzer cargo metadata flow that reports "updating crates.io index" after startup or cleanup; done means opening the project no longer unnecessarily blocks on index updates when offline.
