LightSpeedRe - Launch optimizations

LightSpeedRe 2.0.1

• Add startup.verifyJarHash in config/lightspeed-common.toml, disabled by default. When enabled, persisted per-mod resource existence, namespace and file-list caches use the complete JAR SHA-256. Each JAR is hashed once per launch; restart after changing the option. Switching modes rebuilds these caches.
• Keep the existing default cache identity and the Agent's independent scan/image validation. Each release JAR includes its bootstrap Agent.
• Use binary-search ranges over sorted resource names instead of constructing every directory-prefix range. Read cached resource bytes when the supplier is opened, avoiding copies and CRC work for resources that are filtered out. Validation: distribution packaging and cache-key checks passed. Full client startup with the optional hash setting enabled has not been verified. Startup times depend on the pack, Java, heap and cache state; this release makes no fixed-time guarantee.

• 新增 startup.verifyJarHash，默认关闭。开启后，持久化的资源存在性、命名空间和文件列表缓存使用完整 JAR 的 SHA-256；每次启动同一 JAR 只计算一次，修改选项后需要重启。
• 保持默认缓存规则及 Agent 的独立扫描、资源镜像校验，发行 JAR 已内嵌 Agent。
• 发行包结构与缓存键检查通过；开启哈希模式后的完整客户端启动尚未验收，启动时间随环境和缓存状态变化。
