Revert the desktop hotkey: a new crate needs a Cargo.lock this machine cannot write

`42e06da` added `tauri-plugin-global-shortcut` to Cargo.toml without updating
Cargo.lock, and every cargo invocation in CI passes `--locked`. Both desktop
jobs failed on the same line before compiling anything:

    error: cannot update the lock file ... because --locked was passed

So this says nothing about whether the code is right — clippy never ran. The
gate did exactly its job.

There is no Rust toolchain on this workstation (rule 10 — CI verifies), and a
lockfile is the one artifact CI is deliberately forbidden to generate. Hand-
writing the entries is not a real option: it needs the exact checksum and the
whole transitive tree, and a wrong checksum fails harder than a missing one.

Reverted rather than left red, because a red `dev` blocks everything behind it
and the Android half of #1899 is green and unaffected at c8318c3. The work is
intact in 42e06da and comes back with `git revert 5e0c...` once the lockfile
exists — nothing here needs rewriting.
