Task 632: Replace waitForTimeout with Event-Based Waits

Status: DONE

Problem

17 instances of waitForTimeout() in E2E tests create flaky tests. Hard-coded delays may be too short in slow CI or unnecessarily slow locally.

Solution

Replaced all 17 waitForTimeout instances with event-based waits:

• DAG viewer init (10 instances): waitForSelector("#dag-viewer .dag-filter-bar", { timeout: 10000 })
• 3D viewer init (5 instances): controls.waitFor({ state: "visible", timeout: 10000 }) with try/catch skip
• Slider input (1 instance): expect(infoLabel).not.toContainText("最新") assertion
• Scene switch (1 instance): waitForFunction checking text change
• Tab switch (1 instance): expect(panel).toBeVisible() assertion
