Refactor firmware verifier into staged functions Restructure scripts/verify/firmware/analysis.mjs for readability without changing behavior. - Move prerequisite checks into checkPrerequisites() - Split the main flow into stageCli, stageMcp, stageExt4 and stageGhidra - Extract timeouts and size limits into named constants - Rename cli/call helpers to runCli/callTool Checks, order of operations, error messages and env vars are unchanged.
