Stop returning grant strings across UniFFI; approve yields typed outcomes and
pull/resume use transfer id plus path or ReceiveOutputSink. Document the
pairing/targeted event catalog and cover Android MediaStore-style sink contracts.

Adds the opt-in foreground check and an explicit Check now, the waiting-to-
be-delivered list on the sender side, and honest reporting when a send could
not be delivered: a closed app is a delay, not a success nobody received.
The setting is off by default and its footer states that checking reveals
app-open times to remembered devices, since that is the reason it is a
setting at all.
Records in the design doc that this shipped as one global toggle rather than
the per-contact opt-in originally specified.
Sender-held offers with a bounded foreground pull instead of push
infrastructure. Records that APNs is out of scope and that mobile-to-mobile
with both apps closed is unsupported.
Design for remembering devices after a transfer and sending to them without
a new invitation. Grant-based contacts so consent and revocation are
enforceable by the party being remembered. Local network discovery
considered and deferred (Appendix A).
