Document the by-design tf.io and tf.train benefit exclusion

The whole-namespace exclusion is deliberate although both namespaces
mix builders with tensor-producing ops: the benefit signal asks whether
graph execution accelerates the function's work, and parsing or
decoding input is preprocessing, typically per-element work living in
tf.data pipelines that trace their map functions independently. The
corpus tally backs the premise (roughly 120 builder and checkpoint
references against 6 op call sites, no observed misjudgment), and a
typed result from such an op still counts through the tensor-type
branch. Narrow to a builder-name blocklist only if a decode-heavy
function is ever wrongly declined, with the instance in hand.

Closes #715.
