Android half of ios#36, spec §6.27. `shot` joins the control kinds, so a
build that does not know it stays quiet rather than rendering JSON.
🔴 The care is in refusing to let the absence of a notice mean anything.
The device that took the screenshot reports it, so a modified build, a
second phone, or a screen recorder produce nothing. A notice means one
was probably taken; no notice means NOTHING, and nothing counts them.
⚠️ Android's half of the asymmetry is stated rather than hidden. There is
no screenshot callback at all before API 34, and the one added there does
not cover screen recording — so the disclaimer says that, in those words.
Claiming a symmetry with iOS that does not exist would be worse than the
gap, because somebody would rely on it.
⚠️ Only where a timer is set, and the timer check comes before the
rate-limit check so a suppression window cannot make an untimed
conversation start reporting.
⚠️ Last-notice times are in memory. Persisting them would store who
screenshotted whom on disk to enforce a five-second window.
