Pull request overview

This pull request adds form data persistence and GitHub token validation to handle Cloudflare bot protection challenges. When a 403 response is received (interpreted as a CF block), the implementation is designed to save form data to LocalStorage and refresh the page to pass bot detection.

Changes:

• Added GitHub token validation before API calls in the worker
• Added LocalStorage-based form data persistence and recovery in the HTML form
• Added CF block detection to trigger page refresh on 403 responses

• When form submission fails (either with an error response or network error), the retry state should be cleared from localStorage. Otherwise, if a user refreshes the page after a failed submission, the form will auto-submit again, potentially creating an unwanted retry loop. Add clearRetryState() calls in the error handling paths.

                } else {
                    showError(result.error || '提交失败');
                }
            } catch (err) {
                console.error(err);
                showError(err.message || '网络错误或请求失败');
