docs: sanitize CHANGELOG #18 entry + remove obsolete Known issues section

Browse Source 
Two-part cleanup:

- CHANGELOG.md #18 entry: rewrite the symptom description without
  naming the specific third-party site that originally reported it.
  The technical root cause and fix are unchanged.

- README.md: remove the entire "Known issues" section. Its only entry
  was the headless=True alt-desktop crash from #18, which was fully
  fixed in 0.1.7 / firefox-7. Leaving the workaround instructions in
  the README would have misled users into adopting them
  unnecessarily. New issues can be added back as they're found; the
  default state is "no known issues".

Pre-push: 402 unit + integration tests pass.

## Known issues
### `headless=True` on Windows can cause tab crashes on sites with heavy cross-process navigation
Reported as [#18](https://github.com/feder-cr/invisible_playwright/issues/18) (`id.sky.com` and similar). On Windows, `headless=True` runs Firefox headed on a hidden alt-desktop created via `CreateDesktop`. Some sites (id.sky.com, anything else loading Adobe AppMeasurement in a way that triggers cross-process navigation) end up firing `page.on('crash')` after about 10 seconds. The cause is a window-parenting interaction between the alt-desktop and the GPU/content processes; the workaround is one of:
```python
# Option A — keep the visible window (no alt-desktop)
with InvisiblePlaywright(seed=42, headless=False) as browser:
...
# Option B — run inside Xvfb on Linux (alt-desktop bug is Windows-only)
```
The visible window case works on every site we've tested. Linux + Xvfb is unaffected.
