A pane's split right/down menus offered only New terminal. They now list the same AI tools as the tab bar's + menu (newTabTools/newTabBody, shared from ConsoleTabs), started bare in the first free slot on that side of the pane. The tab bar's Tools menu is gone: its readme run hit 409 ERUNLIVE whenever slot 0 was live (always, in the session view) and depended on a personal skill; MCP sync and the dev-sync check served the dormant ship-feature-lane pipeline. The sidebar row menu's readme item goes too. The routes stay, reached by `agenthub lanes mcp sync` and `agenthub lanes sync-base`. Also: the home's Memory header and file tabs no longer shrink (a long file squeezed the tab row and clipped it).
