Print Environment Variables Matching Pattern
Quick audit of env vars by prefix — useful when debugging containerized apps that read from `STRIPE_*`, `DB_*`, etc.

Go
os.Getenv with Defaults
`os.Getenv` returns "" when unset — easy to miss. Wrap it with a typed helper that supplies defaults and parses numerics. Saves boilerplate at every config-read site.
Python
Stdlib .env Loader (no dependency)
Parse a `.env` file into a dict and optionally export to os.environ. Skips comments and blank lines, strips surrounding quotes — no python-dotenv dependency needed.
