pi-ai's getModel/getModels does not know about the Fireworks providers
(fireworks, fireworks-firepass); both live under our local model-resolver
because Fireworks speaks the Anthropic-compat endpoint with Bearer auth
at https://api.fireworks.ai/inference, not pi-ai's built-in catalog.
Three call sites were still hitting pi-ai directly and failing silently
for Fireworks:
1. connector-model-policy.ts — listProviderModels() caught the pi-ai
throw and returned []. The "Fire Pass (CEO runtime)" card in the
Team Models onboarding step therefore showed "暂无模型 / 已启用 0/0",
blocking users on Fire Pass from continuing onboarding.
2. worker/worker-runner.ts — getModel() threw mid-run when the selected
connector was Fireworks, so the worker could never actually execute
an agent turn against Fire Pass or the curated Fireworks model set.
Now uses resolveModel() + the Fireworks-specific Bearer header from
resolveExtraStreamHeaders() so streamSimple hits the correct endpoint
with the correct auth.
3. agent-runtime/cost-writer.ts — cost observation silently wrote
amount_usd=null for Fireworks runs because getModel() threw inside
the try/catch. Now resolves via resolveModel() so the Fireworks
curated contextWindow/maxTokens are visible to calculateCost().
