Hongming Wang e6eda38318 fix(a2a-client): negative-cache registry failures in enrich_peer_metadata 
Self-review on PR #2471: failure outcomes (4xx/5xx/non-JSON/network
exception) weren't writing to _peer_metadata, so a peer with a flaky
or missing registry record re-fired the 2s-bounded GET on EVERY
push. The cache became a no-op for the exact failure scenarios it
most needs to defend against, and the poller thread stalled 2s per
push for that peer until the registry came back.

Cache the failure outcome as `(now, None)` so the TTL window
suppresses re-fetch. Two new tests pin the behaviour for both
HTTP failures (5xx) and transport exceptions (httpx.ConnectError).

Type signature widens to `dict | None` on the value tuple's second
slot to match the new sentinel; readers already handle `None` as
"no enrichment available" — that's the documented graceful-degrade
contract — so no caller change needed.
