Replace the per-render readdirSync().filter().map(statSync).sort() chain with a single-pass max-by-mtime loop. Drops the O(n log n) sort and the throwaway intermediate array; I/O and resolved-file behavior are identical. Adds the first behavior-lock test for the todo-resolution path. The larger disk-backed cache win from the issue is deferred: statusline is a fresh child process per render, so any cache must be disk-backed with invalidation/atomic-write design that needs maintainer input.
