Subject: [PATCH 2/2] fix: skip CLI download in build.rs when DOCS_RS env var
 is set

docs.rs builds in a sandboxed environment without network access.
The build.rs script was failing because it tried to download the
Copilot CLI binary. Detect the DOCS_RS environment variable (set
automatically by docs.rs) and skip the download, similar to the
existing COPILOT_SKIP_CLI_DOWNLOAD escape hatch.
