Linux: cargo fmt --all -- --check fails on linux branch (Fast checks CI red)

[Seha16]

Summary

The linux branch fails cargo fmt --all -- --check under the pinned toolchain, so the Fast checks job in .github/workflows/build-linux.yml is red. The format step runs first, so build / clippy / tests never execute in that job.

Reproduce

From linux/, on the pinned toolchain (rust-toolchain.toml -> 1.93, rustfmt 1.8.0):

cargo fmt --all -- --check

Exits non-zero with formatting diffs in:

• crates/app/src/ui/app/mod.rs
• crates/app/src/ui/browse_tab.rs

The drift is whitespace / line-wrap only: a stray blank line plus a few builder chains that fit within max_width = 120 and should be collapsed onto one line.

Environment

• Toolchain: 1.93.1, rustfmt 1.8.0-stable, matching CI's dtolnay/rust-toolchain@1.93.
• rustfmt.toml: edition = 2024, max_width = 120, use_small_heuristics = "Default".

cargo clippy --all-targets -- -D warnings, cargo build --workspace, and cargo test --workspace --lib all pass locally. Formatting is the only failing gate.

Fix

Run cargo fmt --all. Pure formatting, no logic change (2 files, +4 / -12).
