docs(donut): near-miss LEAD rule — offer weak-but-named candidate, don't fabricate

Refines the anti-fabrication miss-handling into three explicit outcomes: firm recall
(answer, grounded), near-miss (a specific named candidate surfaced weakly -> offer the
NAME the tool returned as a tentative "do you mean X?", never invented detail, confirm
before recalling in full), and true blank (in-character deflect). Previously a weak-but-
named hit was flat-dismissed, throwing away a real lead. The anti-fabrication invariant
is unchanged — she offers only a name the tool truly returned, never invented substance.
Live-patched + verified against b181 (the "dangerous crown" case now names/offers the
Crown of the Sepsis Whore; no firm-hit regression).
