fix: exclude bot/ from Next.js build and lint

tsconfig.json included **/*.ts but only excluded worker/**, not bot/**.
This caused next build to type-check bot source files whose dependencies
aren't installed in the root node_modules, breaking CI.

- Add bot/** to tsconfig.json exclude array
- Add bot/** and worker/** to eslint globalIgnores
