Expand description

AR.3: bound a desired watch set to at most cap directories. The active buffer’s directory is always kept (the file you’re looking at must be watched); the remainder fill deterministically (sorted) up to cap. Excess dirs are dropped — their buffers rely on the on-activate stat fallback. Pure, so the cap logic is unit-testable without a filesystem.
