fix(deps): bump @stacksjs/bun-router to ^0.0.16 (0.0.14 shipped no dist)

The API server (server/index.ts -> src/router.ts) failed to start with
"Cannot find module '@stacksjs/bun-router'". Root cause: the published
@stacksjs/bun-router@0.0.14 tarball is missing its dist/ directory (its files
field claims ["README.md","dist"] but dist was never published), so the exports
target ./dist/index.js doesn't exist. The caret range ^0.0.14 locks to 0.0.14
(caret pins the patch for 0.0.x), so install never moved off the broken version.

0.0.15 and 0.0.16 ship dist correctly (verified against the npm tarballs). Bump to
^0.0.16; the API server now boots ("API running at http://localhost:3001") and
`import { Router }` resolves.
