release: 0.1.7 - pin to firefox-7 (issue #18 real fix)

Browse Source 
Bumps BINARY_VERSION to firefox-7 which ships the real fix for issue #18
(id.sky.com tab crash on Windows headless=True).

firefox-7 contents:
- Canvas2D getImageData stealth spoof moved from read-only mapped surface
  to JS Uint8ClampedArray writable buffer (commit 2e17b4871f93 in
  invisible-firefox). Fixes the segfault on GPU-backed canvases that hit
  during page unload.

Paired with the wrapper-side security.sandbox.content.level=4 workaround
shipped in 2e0adbd (this repo), the combination resolves both halves of
issue #18: cross-process navigation crash in loop AND segfault at close.

End-to-end tested with InvisiblePlaywright headless=True + UK proxy on
id.sky.com: page survives 30s+, no crash in loop, no crash at close.

firefox-6 was rolled back when its partial-fix hypothesis turned out to
be the wrong root cause. Skipping straight to firefox-7.

### Fixed
- [#18](https://github.com/feder-cr/invisible_playwright/issues/18): Tab crash on `id.sky.com` and similar sites when running with `headless=True` on Windows. Two separate bugs that only triggered together: (1) the Chromium content sandbox at default level 6 puts content processes on `kAlternateWinstation`, but the wrapper hides the browser window on its own alt-desktop (`CreateDesktop` for headless on Windows). Mismatched desktops → cross-process navigations (Adobe AppMeasurement on id.sky.com triggers them) couldn't reparent windows → content process exits cleanly and Playwright fires `page.on('crash')`. (2) The canvas2d `getImageData` stealth spoof wrote to a read-only mapped `DataSourceSurface`. On GPU-backed canvases that memory is write-protected → segfault during the final `getImageData` id.sky.com runs at page unload. Wrapper now sets `security.sandbox.content.level=4` in the alt-desktop workaround set, and `firefox-7` ships the source fix that moves the noise to the JS array's writable backing buffer. Reporter: [@gamefireat123-eng](https://github.com/gamefireat123-eng).
### Changed
- `BINARY_VERSION` bumped from `firefox-5` to `firefox-7`. `firefox-6` was rolled back when its partial fix turned out to be wrong (the iframe-burst hypothesis was a dead end; bisection in the evening found the real two-bug cause documented above).
