What does this PR do?

• Problem: the one-line description of the library reads awkwardly: "macOS/iOS/tvOS - enabling fast, in memory, prefix based, string searching, using a Trie." The compound adjectives have no hyphens, the commas break the sentence, and "Trie" has a capital letter although it is a common noun, like "tree".
• This PR: rewords it to "A simple library for macOS, iOS and tvOS that enables fast, in-memory, prefix-based string searching using a trie." in the README and in the podspec summary and description. The GitHub repo description already uses the same text.
• Risk: none. Text only. The podspec change does not reach CocoaPods, because 3.0.0 is already published there and Trunk becomes read-only on 2026-12-02.
