v0.70.1

Claude Desktop on Windows is an MSIX package. Files the server wrote under
AppData really landed in the package's own LocalCache folder, and the engine
downloaded there could not be started from the AppData path: the first
`browser_open` of every session answered `[Errno 14001] ... side-by-side
configuration is incorrect`, and every tool after it said the browser was not
open. Measured by driving this server inside a packaged process with an
in-memory MCP client: with invisible-core 34.29.0 it fails exactly so, with
34.30.0 open, navigate, snapshot, type, click, read, screenshot and close all
work. Reported in invisible_playwright discussion #256.

The fix is in invisible-core 34.30.0, pinned by invisible-playwright 0.25.6.
The floor moves to 0.25.6 because a cached uvx environment keeps what it
resolved, and only a floor makes it resolve again; the suite's core floor
moves with it. No code in this package changes.
