v1.3.16 - Allowlist voucher minting + rate-limit hardening

SeaDrop allowlist minting via OpenSea voucher, with the correct custom-chain slug (Robinhood was querying 'ethereum' -> DropNotFound).

• Pre-warm + pre-sign the voucher during pre-arm so T0 is broadcast-only; never fall back to a doomed public mint when no public stage is live.
• Rate-limit hardening: OpenSea returns limits as HTTP 200 'Too Many Requests' (not 429) -> detected + retried with backoff; voucher calls rotate an API key; a global voucherSem caps the fetch burst.
• Settings: API Keys tab; multi-threaded, streaming, live-count free-key grab over a proxy group.
• Manage Funds: searchable wallet pickers.
• Per-wallet stage-open to minted latency shown on success (e.g. 'minted 2213ms block N').

Auto-update: the app downloads the zip asset below and swaps zyper-bot.exe + web/.

v1.3.15

Advanced listing repricer: floor now excludes your own wallets (no self-undercut spiral), lowering a price posts a cheaper listing with no cancel/gas, settings modal (interval/offset/mode/min price), min interval 15s -> 1s, auto-drop sold NFTs, XSS fix.
