Hall of Helix needs a credential-safe render that returns a provenance
receipt and refuses a batch before the quote exceeds its cap. OpenRouter
is the only client; the model and the live budget stay with the founder.

Add pluggable balance registry, OpenRouter credits/key limit client,
and llm-connect balance with one-shot --provider that does not change
library defaults.
Add moonshotai/kimi-k3 as OpenRouter basemodel default after live smoke,
USD→EUR cost conversion, append-only usage ledger, and CLI run/cost/spend
week commands with token and euro reporting.
