scripts/setup-env.ts imports an unused glob dependency with a leftover TODO-style comment

[vjuliaife]

Description:
scripts/setup-env.ts imports globSync from "glob" with an inline comment reading "we might not have glob installed, but we can use fs.readdirSync recursively or just hardcode apps/*" — the import is never used since the script falls back to a hand-rolled findEnvExamples recursive walker. This is confusing dead code that looks unfinished and adds an unnecessary dependency.

Acceptance Criteria:

• Remove the unused import { globSync } from "glob" line and the leftover comment
• Verify "glob" is actually a declared dependency or remove it from package.json if no longer needed anywhere
• Run npm run setup-env against a clean apps/ tree to confirm behavior is unchanged
• Add a short header comment explaining the recursive .env.example discovery approach
