readExcerpt, ReadNote and ReadScoped now read through brainfs (os.Root, regular files only, type checked on the opened handle), so a symlink swapped in after a check is not followed and a FIFO does not hang the reader. ReadRegularMax bounds the read itself with io.LimitReader(max+1). notes.Target carries the brain root.
Refs #157. Adversarial review round 2: PASS (round 1 BLOCKED: unbounded read, rule-9 test names).
