No behavior change.
Adding `filePermissionsSentence` in decc673a inserted it directly under
`footerMessage`'s doc block, which left two block comments stacked and each
attached to the wrong function: `footerMessage` was undocumented, and its
"why not `secretStorageLabel`" rationale read as though it were about the
permissions helper, which it is not.
Moves that block back above `footerMessage`, and drops the inline comment
inside it that now duplicated the new helper's doc — and had gone stale
besides, since it still described two permission states rather than three.
Caught by @mcp-inspector-v2-f1 on a read of the pushed commit.
