Add bounded model checking for loop analysis

[rahuldass19]

Which engine does this affect?

Code Verifier

Is this feature deterministic?

Yes - Pure symbolic/math/logic

Problem Statement

Currently the verifier cannot handle loops/recursion safely - it may explore too many paths (path explosion problem).

Proposed Solution

What needs to be done

• Implement loop bounding (limit iterations to configurable depth)
• Add recursive depth limits
• Create "critical path" prioritization

Skills needed

• Python
• Understanding of symbolic execution

Alternatives Considered

No response

• I have read CONTRIBUTING.md
• This is NOT an enterprise feature (audit, SSO, RBAC)
