Introduces a shared runWithFallback helper that wraps primary model
attempts with an optional fallback. On primary failure (non-abort),
the fallback runs once and metadata is stamped on the node so the UI
can render a "Fallback used" badge. Fallback is skipped when primary
and fallback resolve to the same provider/model to avoid double-billing.
Wired through all generation executors (nanoBanana, generateVideo,
generateAudio, generate3d, llmGenerate) with accompanying tests.
JSON-compatible with Node Banana Pro: fallbackModel and __-prefixed
metadata fields match NBP's shape for clean config round-trips.
