v3.15.1 🏹🌌 The Great Nebula in Orion

TL;DR

A small patch release on top of 3.15.0. We recommend all users update.

• Keysend amounts — webln.keysend() now only accepts the amount as a whole number of sats, either a number (21) or a string of digits ("21"). Decimals, exponent notation ("21e3"), whitespace, signs and zero are rejected with an Invalid amount. error before any prompt is shown. Websites that already pass plain integers are unaffected. The same check applies to keysend payments started from the extension itself.
• Build and tooling — updated browserslist data, GitHub Actions on Node 24, and a webpack plugin update that removes deprecation warnings.
