修复 session_id 回绕导致的迟到事件误匹配

[H-Chris233]

User description

概述

• 将 coordinator 内部听写 / QA session 守卫从 wrapping u64 改为 UUID
• 保留原有 captured session id 比较逻辑，避免迟到 RecorderError / startup continuation 误命中新会话
• 同步更新 Windows IME 预备会话槽和相关回归测试里的 session id 类型

验证

• cargo check --manifest-path openless-all/app/src-tauri/Cargo.toml
• cargo test --manifest-path openless-all/app/src-tauri/Cargo.toml coordinator::tests:: --lib
• git diff --check

说明

• 额外跑过 cargo test --manifest-path openless-all/app/src-tauri/Cargo.toml --lib，当前 beta 上存在无关失败：types::tests::legacy_hotkey_trigger_still_produces_effective_key_codes。本 PR 未修改 types.rs。

Closes#297

PR Reviewer Guide 🔍

Here are some key observations to aid the review process:

🎫 Ticket compliance analysis 🔶 297 - Partially compliant Compliant requirements: Replaced session ids with UUIDs. Preserved session-id equality checks for late-event / startup-race handling. Updated Windows IME prepared-session helpers and related tests to use UUID session ids. Added/updated regression tests for stale-session isolation. Non-compliant requirements: None identified from the diff. Requires further human verification: None.
