What is new in Trailer 1.9.0

#### This is a macOS-only release, the iOS version needs some serious rework.

- No new features, but a lot of functionality and performance improvements, including benefits from using the latest Xcode and Swift toolchain.
- Trailer now requires macOS 15.6 or later (1.8.11 ran on macOS 11 and up.)
- Disclaimer: AI/LLMs have been used as part of this (and most probably future) work. I hope this isn't a deal breaker for most users, and I do find LLMs a useful addition to my software development toolkit, but I do recognise that it's important to be upfront about its use.
- The menu bar item has been rebuilt from scratch. It's now rendered as a standard template image handed to the system status item, instead of a hand-drawn custom view. It looks correct on macOS 26 Tahoe's new menu bar, follows light/dark mode and tinted menu bars properly, and highlights correctly while the menu is open.
- New app icon built for macOS 26, with light, dark and tinted variations.
- Menu bar text and icon colours are now tuned per macOS version, so counts stay legible on older and newer systems alike.
- The menu now sizes and positions itself correctly when the menu bar is set to auto-hide — it measures the real menu bar height instead of assuming a fixed one.
