Both sides extended the OAuth flow entry points: main threads a login hint
through GetOAuthFlow/NewOAuthFlow, this branch threads a sessionExtend flag.
The merged signatures carry both.
client/android/login.go keeps main's structure — the hint reaches the flow
through GetOAuthFlow rather than a loginHintSetter assertion, profile email
helpers live in client/mobile, and runOAuthFlow is the shared driver — with
this branch's sessionExtend plumbing and wrong-account retry layered on top.
The branch's runInteractiveFlow is dropped in favour of runOAuthFlow.
client/android/ssh_client.go is new from main and merged without conflict,
but calls NewOAuthFlow; SSH login is a fresh login, so it passes false.
management.pb.go regenerated with the pinned protoc-gen-go v1.26 from
generate.sh. The .proto merged cleanly: main's LazyState and proxy_embedded
are disjoint from this branch's SessionExtend field.
