Fix #241

Add buildLaunchPersistentContextOptions() and humanizeContext() helpers function.

This PR is a follow-up to the #244 and #262 PRs.

@Cloak-HQ Would it be possible for you to review my PR?

There are often other changes in js/src/playwright.ts. This causes conflicts that I have to resolve.

Thanks for the PR. Before reviewing the API change, could you clarify the concrete use case? Is Playwright-ghost solving a specific limitation or failure you encountered with CloakBrowser’s current wrapper, or is the goal primarily architectural compatibility with its plugin system? If specific plugins are required, which ones and what capability do they provide that CloakBrowser currently lacks?

This PR is a follow-up to:

• feat(js): export composable launch helpers #244, which adds buildLaunchOptions() and humanizeBrowser() to launch().
• feat(js): export buildContextOptions helper #262, which adds buildContextOptions() for launchContext().

My PR completes these additions with buildLaunchPersistentContextOptions() and humanizeContext() for launchPersistentContext(). There are now methods to configure the parameters for all three launch*() methods and to humanize their return objects (Browser or Context).

Playwright-ghost adds a plugin system to Playwright. Plugins allow you to modify the input parameters and return values of methods. However, you cannot modify a method directly. That’s why I need the build*() and humanize*() methods.

Playwright-ghost and CloakBrowser have different goals. Playwright-ghost is more general-purpose with its plugins, while CloakBrowser is more focused on stealth.
