Subject: [PATCH] feat(shell): add OpenSSL env vars for cargo builds on Linux
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Set PKG_CONFIG_PATH, OPENSSL_DIR, OPENSSL_LIB_DIR, OPENSSL_INCLUDE_DIR
in both bash and fish so cargo can find OpenSSL without nix-shell.

Fixes: cargo build failing with "openssl-sys: system library not found"
