feat(trailing-slash): add strict option to support wildcard routes

[yusukebe]

Resolves #3407

Add strict option to trimTrailingSlash and appendTrailingSlash middleware.

When strict: true, the middleware redirects before executing handlers, which fixes the issue where trailing slash handling doesn't work with wildcard routes (*).

app.use(trimTrailingSlash({ strict: true }))

The author should do the following, if applicable

• Add tests
• Run tests
• bun run format:fix && bun run lint:fix to format the code
• Add TSDoc/JSDoc to document the code
