Runtimes like Hermes and LangGraph accept any one of several LLM
provider keys (OpenRouter OR OpenAI OR Anthropic OR Nous-native).
Before this change, the missing-keys modal treated all supported
providers as simultaneously required — a fresh user on Hermes was
asked for three parallel API keys when any one suffices.
Introduces RUNTIME_PROVIDERS in deploy-preflight.ts as the canonical
per-runtime provider list (label, envVar, note). checkDeploySecrets
now returns all alternatives as missingKeys when nothing is
configured, so the modal can offer a picker.
MissingKeysModal dispatches between two render paths:
* ProviderPickerModal — radio list of supported providers, a single
env input for the chosen one. Saving that one key satisfies the
preflight. Activated whenever the runtime has ≥2 provider choices.
* AllKeysModal — legacy parallel-inputs UX, all keys must be saved
before deploy. Kept for single-provider runtimes (claude-code,
gemini-cli) and callers that pass unrelated-key lists.
Dual-mode preserves the pre-existing contract for every caller while
fixing the multi-provider UX. All 930 canvas vitest tests pass.
