// BenchmarkResetHardIgnoredDir measures the cost of HardReset over a tree

// that contains a large gitignored directory (e.g. node_modules-like).

// resetWorktreeToTree walks the worktree to discover tracked files that are

// missing or stale on disk. Without the IgnoreScope optimization, this walk

// descends into every gitignored subtree before the loop body discards the

// resulting Delete actions. With the scope engaged, the entire ignored

// subtree is skipped at enumeration time, so cost stays roughly flat as the

// number of ignored files grows.

// Mirrors BenchmarkStatusIgnoredDir to make the speedup directly comparable

// across the two operations.
