Vance Ingalls 36075c6797 fix(engine,producer): classify blank vs psnr from a structural field, not the error message
Deepwork's request-changes on #2411 (twice): deFallbackReason's blank/psnr
split still ran /blank/i.test(err.message) even after this PR's stated goal
of moving off message-text parsing — a reworded message, a translated
string, or a differently-shaped error crossing a module boundary could
silently relabel a blank failure as psnr (or vice versa), corrupting the
soak's telemetry taxonomy.

DrawElementVerificationDetails now carries a required `kind: "blank" | "psnr"`
field, set at all three real throw sites in captureStreamingStage.ts. The
orchestrator derives deFallbackReason from getDrawElementVerificationDetails's
kind instead of regexing the message. Making `kind` a required constructor
argument means any future throw site that omits it fails to compile, closing
the gap for good rather than just at today's three call sites.

New tests in frameCapture.test.ts prove message-independence directly: kind
survives a reworded message that says neither "blank" nor "psnr", and stays
correctly "psnr" even when the message adversarially contains the substring
"blank" — the exact scenario a regex-based classifier would get wrong.
