Fix: rust source inside Submodules are not parsed

[PierreEtienneJ]

Describe the bug

With a lib like

📦 my_crate
 ┣ 📜 Cargo.toml
 ┣ 📂 src
 ┃ ┣ 📜 lib.rs
 ┃ ┣ 📂 my_mod
 ┃ ┃ ┣ 📜 mod.rs   # ✅ Parsed correctly
 ┃ ┃ ┣ 📜 sub_mod.rs     # ❌ Not parsed

Currently, the library correctly parses my_mod/mod.rs, but it does not parse files inside the my_mod directory, such as my_mod/sub_mod.rs.

how to fix

Fix the rust function analyzer::crate_::analyze_crate in the loop.
