fix(Log): restore inherited event properties

[dvd233]

Summary

• restore inherited enumerable properties when expanding logged DOM events, preserving the behavior introduced for touch相关的事件捕获的对象属性不全 #327
• keep safe JSON serialization limited to own enumerable properties
• avoid Svelte 5 reactive deep-reads of host objects with native accessors
• add a touch-event manual regression case and update both changelogs

Root cause

The Svelte log-tree rewrite replaced the previous for...in traversal with Object.keys(). As a result, TouchEvent expansion only exposed its own isTrusted property and omitted inherited fields such as touches, targetTouches, and changedTouches.

On the current Svelte 5 build, rendering those inherited host objects through legacy reactive blocks can also trigger Illegal invocation while Svelte deep-reads native properties. The tree/value updates now run through beforeUpdate, which preserves updates without recursively inspecting host objects.

Verification

• focused assertions for own vs. inherited enumerable keys and unchanged safe-JSON behavior
• npx tsc --build tsconfig.type.json
• npm run build:wx
• npm run build
• npm pack --dry-run --json
• Pixel 10 Chromium: triggered the Touch Event dev case and expanded type, touches, targetTouches, and changedTouches with no page errors
• browser regressions for common objects, circular objects, and a throwing inherited getter

Fixes #609
