Simple standalone Chaumian mint boundary service

This is a simple standalone Chaumian mint boundary service meant for local development and integration. The service operates independently of consensus. It uses JSON contracts outlined in: [*] the HTTP handlers found in server.py [*] the finalized-state lightserver surface detailed in LIVE_PROTOCOL.md It’s just a basic framework, definitely not for production use: [*] file-based state [*] deterministic RSA blind-signing designed for development/testing [*] persistent issuance ledger [*] endpoints for reserve and accounting summary [*] inventory/fragmentation reporting for reserve wallets [*] coin selection policy for max-input and reserve alerts [*] automatic redemption handling using a configured reserve wallet [*] lightserver-based redemption finalization (pending -> broadcast -> finalized/rejected) [*] HMAC-signed admin requests for operators [*] persistent job queue for notifier delivery [*] optional single-worker lock for draining the queue [*] notifier secret references handled through a pluggable secret backend [*] signed reserve attestations and audit exports [*] no federation [*] no multi-operator quorum custody Endpoints [*] POST /deposits/register [*] POST /issuance/blind [*] POST /redemptions/create [*] POST /redemptions/approve_broadcast [*] POST /reserves/consolidate [*] POST /redemptions/status [*] POST /redemptions/update [*] POST /policy/redemptions [*] GET /healthz [*] GET /mint/key [*] GET /reserves
