The `core.checkstat` configuration is currently stored in the global variable `check_stat`, which makes it shared across repository instances within a single process.
Store it instead in `repo_config_values`, where eagerly‑parsed repository configuration lives. `core.checkstat` is parsed eagerly because it controls how `match_stat_data()` and related functions decide file freshness; a lazy parse could lead to unexpected behavior or complicate libification. This preserves the existing eager‑parsing behavior while tying the value to the repository it was read from, avoiding cross‑repository state leakage, and continuing the effort to reduce reliance on global configuration state.
Update all references to use `repo_config_values()`.
