fix(cli): add SSL verification option for client transports

[yumosx]

Description

Add support for disabling SSL verification when verifySsl flag is false by providing a custom HTTPS agent. This allows connections to servers with self-signed certificates or in development environments where SSL verification needs to be bypassed.

Summary by cubic

Adds an optional SSL bypass for MCP SSE and HTTP client transports. When requestOptions.verifySsl is false, connections to self-signed or dev servers work; default behavior remains unchanged.

• New Features
  • Use https.Agent({ rejectUnauthorized: false }) when verifySsl is false for SSE and streamable-http transports.
  • No agent is created when verifySsl is true or unset.
  • Added tests covering both transports and verifySsl states.

^{Written for commit 173b9db. Summary will update on new commits.}
