Extract the pre-first-image retry from normal_operation() into a templated bootstrap_loop() helper in operation.h so the loop body becomes unit-testable. Add four tests against it: two that verify the X-Panel-Id header is sent on every poll and matches the compile-time PANEL_ID (a silent server-side mis-routing risk if dropped), and two that exercise the loop's exit-on-deep-sleep vs. iterate-while-204 behaviour. Wire --coverage into env:native-test (compile + link via a post-script) so `gcovr -r . --filter src/` produces a real number, and ignore the stray *.gcov files gcovr drops at the repo root.
