fix(learn): v1 also withholds function length (a leak by construction)

The leak audit found facts.function_lines separating fixed from vulnerable pair
sides (a fix guard lengthens the function: 0.80 untrusted_destination, 0.75
config_secrets). Input profiles may now name single features; v1 withholds the
engine and the function length from prompts, retrieval and the proposer summary.
A withheld feature keeps its instrument block in the distance (state still counts).
