Three fixes for PR #1377 review:
1. CI flake (sendImage_privateChatProcessesAndTransfersImage): the
panicClearAllData / clearCurrentPublicTimeline detached utility-priority
tasks delete the real ~/Library/Application Support/files tree, which the
test process shares. The wipe fires at a nondeterministic time and raced
the sendImage test's JPEG in files/images/outgoing (write then re-read),
so prepareImagePacket threw and the test timed out. Both wipes are now
skipped under tests (existing TestEnvironment.isRunningTests pattern);
this also stops test runs from deleting the developer's real media.
2. Codex P1: ping packets are unsigned, so keying the pong rate limiter on
packet.senderID let one connected peer rotate forged sender IDs to bypass
the 5-per-10s budget. The limiter now keys on the ingress link (the
directly connected peer that delivered the packet); the pong still goes
to the claimed sender. Regression test proves rotating senders over one
link exhaust one budget (fails 10 vs 5 pongs on the old code).
3. Codex P2: /ping output arrived up to 10s later and was routed from
selectedPrivateChatPeer at callback time, misrouting the result after a
chat switch. The origin conversation is now captured when the command is
issued (CommandOutputDestination) and deferred output is routed there:
a DM result lands in the origin chat's history even if deselected, and a
mesh-timeline result pins to #mesh instead of the active channel.
