Root cause of the multi-user-basic/nc32 failure: the appstore installs
DIFFERENT astrolabe versions per NC major (min-version jumped 31->32 at
astrolabe 0.25.0). NC31 pulls astrolabe 0.24.0 (search box = NcTextField ->
<input>, submits on Enter); NC32 pulls 0.29.0 (search box = NcTextArea ->
<textarea>, submits on Ctrl/Cmd+Enter). The test's `.mcp-search-input input`
selector + Enter never matched the textarea on nc32, so it timed out after the
SPA mounted fine. This was latent all along but masked on nc32 by the
vector-sync gauge flake, which failed the test earlier; fixing that flake
unmasked it.
Fix: match either `.mcp-search-input textarea, .mcp-search-input input` and
submit based on the element tag (Ctrl+Enter for textarea, Enter for input).
Verified against a live NC32 + astrolabe 0.29.0 stack: the textarea is found
and Ctrl+Enter fires GET /apps/astrolabe/api/search. All other selectors the
test uses (.mcp-loading/.mcp-error/.mcp-results/scatter3d) still exist in 0.29.0.
