kevinburke/ssh_config's package-level Get/GetStrict use a sync.Once
to load $HOME/.ssh/config once per process and cache the result. That
breaks two things:
* users who edit their config mid-session don't see updates until
kandev restarts;
* e2e tests that write a fresh ~/.ssh/config per test all see the
state captured by whichever test triggered the first lookup.
Open and Decode $HOME/.ssh/config on demand from a local
inheritFromSSHConfig helper. The library still parses the file the
same way — we're just dropping the global cache.
Unblocks the four ssh/config-inheritance.spec.ts cases that wrote a
per-test ~/.ssh/config.
