Markus Hartung 032a3d2f76 fix(sse): provider-response summary used the client's format, not the provider's
providerPayloadCollector (dashboard "Provider Response" panel) was keyed on
sourceFormat (the CLIENT's wire format) instead of targetFormat (the
PROVIDER's — see createSSEStream's own @param doc: "targetFormat - Provider
format", "sourceFormat - Client format"). Whenever a request translates
between two different formats — e.g. a Responses-API client routed to a
plain-OpenAI-chat-completions upstream, the common OpenClaw/opencode-zen
shape — the reducer picked for sourceFormat could never recognize the
provider's actual raw event shape, so it stayed stuck at its empty initial
state. The dashboard's "Provider Response" panel showed a permanently empty
`output: []` while "Client Response" (built from separately-accumulated
state, unaffected by this bug) correctly showed full content — reading as
if the two panels simply disagreed about the same request.

Confirmed live via a wire-level pcap capture (scripts/sre/tcp-close-
analyzer.py) cross-referenced against the dashboard log
(1786032832181-1c6275): the actual response was complete and correct: this
was purely a logging/summary bug, never a wire-format bug.

Fix is mode-aware: TRANSLATE mode uses targetFormat (the provider's true
format); PASSTHROUGH mode keeps sourceFormat, since passthrough has no
separate provider/client format split — nothing gets translated there, and
real passthrough callers (createPassthroughStreamWithLogger) don't even
pass targetFormat.

New regression test reproduces the exact live scenario (Responses-API
source, OpenAI target, real chat.completion.chunk deltas) and asserts the
provider summary reflects them — confirmed it fails with the old
`sourceFormat`-keyed code (reproducing the live `output: []`-style
symptom) and passes with the fix.
