Split pure-config into invisible-core; keep back-compat shims

The seed->fingerprint->prefs logic, binary download, and proxy/geo config
now live in a standalone invisible-core package (zero Playwright), so a
profile manager can reuse it without pulling Playwright in. The wrapper
depends on invisible-core and replaces the moved modules with full-alias
shims: existing imports (public API, submodules, private names) and
isinstance checks keep working unchanged. tests/test_backcompat.py locks
that contract (6 guards). Bumps to 0.3.0.
