Tollgate v0.0.1

First public release of Tollgate, an open-source LLM spend-control proxy in Rust. Early foundation, not production-ready.

Highlights:

• Per-key and global token budgets with a hard-stop before overspend
• Tokens-to-cost accounting per model, currency-agnostic integer money
• Native pass-through adapters for Anthropic and Google Vertex / Gemini
• HMAC-SHA256 API keys under a server-side pepper
• Zero-infra demo (cargo run -- demo) and a production path on Postgres + Valkey
• Cloud Run + Terraform, with secrets sealed in Secret Manager
• Reserve-then-settle enforcement that reconciles from the ledger on restart
