feat(cli): add --exit-on-destroy and --threshold flags for CI/CD gating

Adds two CLI flags documented in the README CI/CD section but missing from
the actual CLI implementation:

- preview --exit-on-destroy: Exit with code 1 when the plan contains
  destructive changes (deletes, replaces). Enables CI gating on destuctive
  operations.
- cost --threshold <float>: Exit with code 1 when the total monthly cost
  delta exceeds the specified value. Enables cost-aware CI/CD pipelines.

Both flags align with the existing README documentation and maintain full
backward compatibility (default behavior unchanged).

Tests: 53/53 passed (49 existing + 4 new for the new flags)
