Kiwi News Protocol v0.3.0 released

Kiwi News Protocol v0.3.0 is a release whose changelog covers versions 0.4.0 through 0.15.0 and an unreleased section, and the article is a changelog rather than a single announcement. The most recent described change, in the unreleased section, chunks trie sync so that each frame is at most 1 MiB, with maxDataLength set to 2 MiB, and all nodes must upgrade together because a 15.0.0 node will not sync with a 14.0.0 node. Version 0.14.0 added text-only posts using data:text/plain URLs with a 2048-character limit, and version 0.12.0 removed the Kiwi Pass NFT-based access control in favor of delegation-only access.
