fix(ide-tools): move run_input above the tests module (#677)
clippy::items_after_test_module failed the workspace clippy run because run_input was defined after the first test module in crates/ide-tools/src/process.rs. Move it above; no code changes. Co-authored-by: a-rookie-of-C-language <186315048+a-rookie-of-C-language@users.noreply.github.com>
