refactor: Clean up test infrastructure + improve test quality (#12074) ## Summary Two sets of improvements to the Rust integration test suite. ### Shared helper refactoring (commit 1) - Adds `turbo_command()`, `git()`, and `combined_output()` to `common/mod.rs` — single source of truth for turbo binary configuration, git operations, and output merging - Migrates 10+ test files from local command builders to shared `turbo_command()` - Eliminates duplicate `replace_turbo_json` from `strict_env_vars.rs` and `run_summary.rs` - Refactors `check_json_output!` macro to use `turbo_command()` internally - Renames `walkdir` -> `find_files_by_name`, removes unnecessary `_inner` wrappers - Fixes duplicate doc comments in `setup.rs` ### Test quality improvements (commit 2) - **Removes brittle hardcoded hashes** from `edit_turbo_json.rs`, `run_caching.rs`, `run_logging.rs`. Tests now assert on hash *relationships* (changed/unchanged) rather than exact hex values. Any hash algorithm change no longer requires updating magic constants. - **Eliminates `thread::sleep(1s)`** in `run_summary.rs` by sorting summaries by cached count instead of relying on ksuid timestamp ordering. This was a classic flake source. - **Reduces `big_status_test` from 10,000 files to 100**. The test proves filenames with spaces are handled correctly — it doesn't need to stress-test I/O. - **Adds meaningful assertion** to `test_single_package_dry_run_pnpm` (was only checking exit code). - Migrates remaining inline git commands in `run_caching.rs` to shared `common::git()`. 22 files changed, ~250 lines removed.
