Strip OIDC token request env vars from Claude session#1011

When id-token: write permission is enabled, ACTIONS_ID_TOKEN_REQUEST_URL and ACTIONS_ID_TOKEN_REQUEST_TOKEN are passed to the Claude session via the process.env spread in parseSdkOptions(). This allows Claude to mint new OIDC tokens, which is an unintended capability. This commit deletes these two variables from the env object before passing it to the Claude SDK. The OIDC flow in token.ts reads directly from process.env and runs before parseSdkOptions(), so it is unaffected. Fixes anthropics#1010
