223306df04The inspector's files come across from the standalone-panel branch and the panel becomes the dock's first tab: the toolbar button toggles the "message-bus" tool through the dock glue, the panel sheds its own dock chrome in favor of a panel-local top bar (the dock owns close), and the entrypoint registers the panel alongside the existing instrumentation install. Capture, views, filtering, retention settings and their tests are unchanged beyond the mount shape; the integration and system specs select through the shared dock chrome.
