/**
 * Hook 系统入口
 *
 * P2-11: 4-hook 管道系统
 *
 * 提供自动上下文注入能力：
 * - SessionStart: 会话开始时注入项目概览
 * - UserPromptSubmit: 用户提交提示时注入工作流状态
 * - PreToolUse: 工具调用前注入上下文约束 + 阶段工具门控
 * - PostToolUse: 工具调用后记录 ledger + 检测阶段转换信号
 *
 * @example
 * ```typescript
 * import { executeSessionStart, executeUserPromptSubmit, executePreToolUse, executePostToolUse } from 'specpow/core/hooks';
 *
 * // 会话启动
 * const context = await executeSessionStart(projectRoot, 'claude');
 *
 * // 用户提示提交
 * const workflowContext = await executeUserPromptSubmit(projectRoot, userInput, 'cursor');
 *
 * // 工具调用前拦截
 * const preResult = await executePreToolUse(projectRoot, 'Edit', toolInput, 'claude');
 * if (preResult.blocked) { // 阻止工具调用 }
 *
 * // 工具调用后处理
 * const postContext = await executePostToolUse(projectRoot, 'Bash', true, toolOutput, 'claude');
 * ```
