Playwright - add java sources to a captured Playwright trace

[antonfilichkin]

Context

Allows attaching java sources to Playwright traces.

Allure only configures Playwright traces to include screenshots and snapshots via

new Tracing.StartOptions()
    .setScreenshots(true)
    .setSnapshots(true)

Playwright allows including java sources by setting PLAYWRIGHT_JAVA_SRC and configuring tracing via

new Tracing.StartOptions()
    .setSources(true)

The problem:

1. Playwright provides trace as .zip binary
2. Playwright doesn't have mechanism to suppress synthetic frames from trace, it only handles its own ones. But with Allure enabled - frame 0 is always synthetic AspectJ-weaving glue inserted by AllurePlaywrightAspect, not the real caller - making Trace Viewer's Source tab useless.
3. Playwright handles trace building on it's binary side

The idea is to add configurable option to allow Allure rewrite sources and remove it's own synthetic frames
Implementation idea:

• Add allure.playwright.trace.sources (default false) to opt into embedding sources in the trace.
• Add TraceStackSourceTrimmer, which rewrites the trace.stacks entry in place: it resolves the first file-backed frame in each stack, falling back to stripping the leading run of recognizable AspectJ/Playwright weaving frames when no frame resolves. Fails open on any error, leaving the trace attached unchanged. With some short-circuits to disable zip/json processing - I.e. binary blobs, sources path not set.
