TypedRoutes doesn't work with trailingSlash config

### Link to the code that reproduces this issue https://github.com/damianfrizzi/next-typed-routes-bug ### To Reproduce 1. Clone repo 2. Run `bun run tsc` ### Current vs. Expected behavior The `typedRoutes` config seems to not respect `trailingSlash` config. If `trailingSlash: true` I'd expect the generated routes to contain a trailing slash but they don't. ### Provide environment information ```bash Operating System: Platform: darwin Arch: arm64 Version: Darwin Kernel Version 24.6.0: Mon Jul 14 11:30:40 PDT 2025; root:xnu-11417.140.69~1/RELEASE_ARM64_T6041 Available memory (MB): 49152 Available CPU cores: 14 Binaries: Node: 22.15.0 npm: 10.9.2 Yarn: N/A pnpm: N/A Relevant Packages: next: 15.5.2 // Latest available version is detected (15.5.2). eslint-config-next: N/A react: 19.1.0 react-dom: 19.1.0 typescript: 5.9.2 Next.js Config: output: N/A ``` ### Which area(s) are affected?
