Connection refusals now record whether something other than the API said no

A rejected connection now records whether your corporate proxy said no rather than the API.

What

WebSocket 403 rejections are now attributed to a source, so a corporate proxy refusing the connection is reported differently from the API refusing it.

Details
  • Telemetry splits into transport_closed_403_nonorigin_cf, transport_closed_403_nonorigin_other and transport_closed_403, with matching recovery events.
  • The close event carries a reject_source field plus streak counters.
  • Credentials-rejected errors gain a _credentials_rejected_nonorigin suffix.
Evidence

transport_closed_403_nonorigin_cf

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
