## Summary
- Fixed documentation that incorrectly claimed you could use `[env]` as
a TOML section to set environment variables directly
- The `env` option in bunfig.toml only controls whether automatic `.env`
file loading is disabled (via `env = false`)
- Updated to show the correct approaches: using preload scripts or
`.env` files with `--env-file`
## Test plan
- Documentation-only change, no code changes
