feat(monitor): add initial support for embedded hyperlight VMM (#140)

[imshubham22apr-gif]

This PR introduces initial support for the Hyperlight embedded VMM. Because Hyperlight is embedded directly within the application binary, this implementation avoids external process orchestration (like QEMU or Firecracker) and instead provides a lightweight monitor that executes the unikernel binary directly with its provided arguments.

How was this tested?

• Unit Testing: Created pkg/unikontainers/hypervisors/hyperlight_test.go to verify that the execution command is correctly constructed both with and without additional command-line arguments.
• Compilation: Verified that the project and the new monitor package compile without errors for the target platform using $env:GOOS='linux'; go build ./....
• Static Analysis: Ran go fmt and go vet to ensure code quality and adherence to Go standards.

• I have read the contribution guide.
• The linter passes locally (go vet).
• The e2e tests of at least one tool pass locally (E2E tests require a Linux environment with KVM/Hyperlight setup).
• If LLMs were used: I have read the llm policy.
