Function install_default_provider 

pub fn install_default_provider() -> SshCliResult<()>

Available on crate feature tls only.

Installs aws_lc_rs::default_provider once for the process.

Call from binary main before any TLS dial and preferably before the Tokio runtime is built (rules: install → log → config → runtime → sockets).

Idempotent: a second call succeeds if the default is already installed (including by another crate in the same process).

Errors

Returns [SshCliError::Tls] when install fails for a reason other than “already installed”.
