Function capture_error_with_scope 

pub fn capture_error_with_scope(
    err: &(dyn Error + 'static),
    provider: &str,
    operation_id: &str,
    upstream_status: u16,
    proxy_status: u16,
    error_type: Option<&str>,
    error_message: Option<&str>,
)

Attach the structured Rust error (with its full source() chain) to the current Sentry scope and capture it as an exception event. This is what gives the issue page a real “Exception” block with the reqwest / HttpError / McpError source chain — without this, all Sentry sees is the tracing-bridge’s flat title + tags.

Pair with report_upstream_error: that one creates the titled/grouped issue, this one attaches the structured context. When the sentry feature is off, this is a no-op.
