The nightly browser suite failed in run-mode-menu-scroll: the short-menu case
opened the stock menu and asserted it needs no scrollbar on a 390x640 phone.
The GitHub Copilot entry made the stock CLI list eleven rows, 562px of content
against a 538px cap, so the menu now scrolls there, which is the cap-and-scroll
behaviour the CSS is written for (and what the other two cases verify). Every
further CLI would have broken the same assumption again.
The case now hides the whole CLI block (the container, since its buttons are
rebuilt from the registry) and also checks the "not stretched" half of its name:
the border-box height must stay under max-height. clientHeight would not do,
since it leaves out the border and a menu stretched to its cap reads just under it.
Visible side effect worth knowing: on a phone about 640px tall the stock Run
dropdown now scrolls by roughly one row. At 900px it fits (564px) unscrolled.

The Run dropdown scroll browser test built WebServer on the fixed port 3290,
which the static port guard (test/test-ports-guard.test.ts, from #556) rejects
for any file outside its shrink-only legacy list, so the CI gate failed on the
landing branch. The test now binds an ephemeral port with new WebServer(0, ...)
and navigates to server.boundPort, and its header records the new convention.

The menu opens upward (bottom: 100%) with no max-height or overflow, so with the stock CLIs plus custom endpoint entries it was taller than the room above the toolbar and its top was off-screen and unreachable, worst on phones. Cap it to the space between the header and the toolbar (dvh, vh fallback), scroll inside it with overscroll containment, and stop its overflow:auto children (history, saved URLs) being squashed.
Tests: a CI-gate source guard and a real mobile-browser test (touch swipe reaches the last entry), which fails without the CSS.
