Function resolve_effective_mode 

fn resolve_effective_mode(
    decl: &ProbeDecl,
    control_id: &str,
    probe_mode: ProbeMode,
    framework_filter: Option<&str>,
) -> (ProbeMode, Option<String>)

Resolve effective mode for a control by consulting the probe’s controls map (custom-framework declaration) first, then controlOverrides (per-framework override), then falling back to the probe-level mode. For framework probes, controls whose frameworkArticles don’t cover the probe’s framework are skipped at the caller — this fn assumes the control is in scope. Returns the resolved mode plus the operator’s audit rationale (reason) when an override applied; None when the probe-level mode was the fallback (no per-control override declared).
