This change introduces new functions to the Go SDK specifically designed for use in ephemeral environments like AWS Lambda, where filesystem access is restricted or undesirable. Previously, using the `zrok` Go SDK required an "enabled" environment on disk (`~/.zrok`), which was created by the `zrok enable` command. This made it difficult to use the SDK from serverless functions. The new functions, `sdk.Enable` and `sdk.Dial`, allow a Go application to: 1. Programmatically enable a `zrok` environment by calling the controller API and holding the resulting Ziti identity entirely in memory. 2. Use this in-memory identity to dial a `zrok` share and receive a standard `net.Conn` object for communication. This eliminates the need for a pre-configured `zrok` environment on disk or a separate proxy process, allowing Lambda functions to act as native `zrok` clients. A corresponding `sdk.Unaccess` function is provided for cleanup, and a new example `sdk/golang/examples/lambda/main.go` demonstrates the complete lifecycle of this new feature.

A corresponding `sdk.Unaccess` function is provided for cleanup. This change also includes: - A generic example in `sdk/golang/examples/lambda/main.go`. - A specific test demonstrating how to integrate with the `go-mssqldb` driver for SQL Server connections in `sdk/golang/examples/lambda/mssql_test.go`.
