[Circuit diagrams] 4 - Show conditionals in circuits based on RIR debug metadata

[minestarks]

This PR completes the feature for rendering classical control flow and conditionals in quantum circuit diagrams. The changes span the compiler, code generation, circuit visualization, and VS Code integration.

Circuit Generation from RIR

• Implemented new RIR-to-circuit conversion (rir_to_circuit.rs module) that reconstructs control flow structure from RIR blocks
• Added structured control flow analysis to properly traverse branches in execution order
• Built logic to handle complex scenarios:
  • Measurement-based conditionals (if-else based on qubit measurement results)
  • Nested conditionals and loops with quantum operations
  • Binary operation short-circuit evaluation
  • Multiple possible values in function arguments based on control flow branches

VS Code Extension Fallback Logic

• Added fallback mechanism: if circuit generation fails due to adaptive profile compliance issues when using "static" method, the extension automatically retries with "classicalEval" method and "Unrestricted" profile
• Preserves existing fallback for result comparison errors in "classicalEval" mode

Usage Example

For Q# code with measurement-based conditionals:

operation TestConditional(q : Qubit) : Unit {
    H(q);
    let r = M(q);
    if (r == One) {
        X(q);
    }
}

The circuit diagram now displays the conditional control flow structure, showing which gates execute based on measurement outcomes, alongside the quantum operations.
