/**
|
|
* Workaround for https://github.com/oven-sh/bun/issues/27802
|
|
*
|
|
* Bun compiled binaries have an empty `process.env` when running inside
|
|
* sandbox environments (e.g. nono on Linux/macOS). On Linux we can recover
|
|
* the environment from `/proc/self/environ`.
|
|
*
|
|
* Keep this in sync with getBunSandboxEnvValue() in
|
|
* packages/ai/src/utils/provider-env.ts. The ai package duplicates the lookup
|
|
* for direct consumers that do not go through this coding-agent entrypoint.
