LightSpeedRe - Launch optimizations

2.0.1hotfix

• Fix directory and JAR-root resource lookups in the bootstrap resource index. Existing directories, including directories used by Mixin companion plugins, are no longer rejected as missing files. Resource-file enumeration remains unchanged.
• Make saved bootstrap JVM parameters explicitly opt-in with startup.installBootstrapAgent=false by default. Default startup removes old Lightspeed JVM/pre-launch parameters and preserves unrelated launcher settings. PCL/HMCL/official version JSON no longer receives duplicated Agent arguments.
• Include META-INF/lightspeed/repair-launcher.ps1 for an instance that cannot reach the JVM because of old missing-Agent paths. Extract it from this JAR, run powershell -ExecutionPolicy Bypass -File repair-launcher.ps1 -GameDirectory "path to the instance containing mods", then restart the launcher. The script only removes Lightspeed-owned settings.

发行包、资源目录查找和旧参数清理已按匹配版本回归。原报告整合包和群友电脑未取得，不能称为原实例复测；不承诺固定启动秒数。
