Skip Solana keypair test when solders is absent; add CI

test_generate_new_wallet hard-failed when the optional `solders`
dependency was not installed: SolanaWallet falls back to a stub
pubkey ("STUB_PUBKEY", 11 chars) and the test asserts a base58
pubkey longer than 30 chars. Guard it with pytest.importorskip
so it skips gracefully instead of failing.

Also add .github/workflows/ci.yml running `pytest -q` on push and
PRs to main across Python 3.10-3.12. solders is intentionally not
installed in CI, exercising the skip path.
