/// Resolve the base directory pidge's config-dir-rooted stores (Microsoft
/// tokens in `auth::file_store`, MCP tokens in `mcp::store`) live under.
///
/// In tests, honors a thread-local override set via
/// [`test_support::with_base_dir`] so tests never mutate process-wide
/// `HOME`/`XDG_CONFIG_HOME` env vars: two independent stores' tests
/// overriding those globally, each behind its own lock, can still race
/// across threads in the same test binary. A thread-local sidesteps that
/// entirely: it's invisible to every thread but the one that set it, so
/// parallel `#[test]` functions never interfere and no lock is needed.
///
/// In production this is always `dirs::config_dir()`.
