Install footprint and published tarball
Each version installed on its own into an empty project with nothing but @nuxt/cli as a dependency, so the tree is exactly the CLI and its transitive dependencies. npm cache is warm and the registry is only consulted for metadata, so install wall time is indicative, not a network benchmark.

📝 WalkthroughWalkthroughEvent formatting now accounts for visible tag width when truncating messages, omits tags for request events, and truncates request headings.

Omit the tag when it leaves no room for the repeat marker.
tagRoom can force a four-column tag ([…] ) even when the budget cannot fit that tag, one message column, and the repeat marker. ScreenOverlay then truncates the complete row and can remove the marker.
Suggested fix
const firstLineWidth = visibleWidth(event.message.split('\n', 1)[0] ?? '')
const tagRoom = Math.max(Math.floor(budget / 2), budget - markerWidth - firstLineWidth - 1)
- const tag = event.tag && !event.request ? styleText(MUTED, `[${truncate(event.tag, Math.max(1, tagRoom - 2))}] `) : ''
+ const tagText = event.tag && !event.request ? `[${truncate(event.tag, Math.max(1, tagRoom - 2))}] ` : ''
+ const tag = tagText && visibleWidth(tagText) + markerWidth < budget ? styleText(MUTED, tagText) : ''

📚 Description
Noticed this running
nuxt devin a small terminal inside my editor. The log view lost its title and its first rows, and some lines wrapped before their ellipsis:This was because
formatEventcut the message to the terminal width and then prepended the consola tag, so tagged lines were too wide. Each wrapped row made the frame one row taller than the screen, which scrolled the top of it out of view.So this PR counts the tag against the width, and
ScreenOverlaynow truncates every visible row as a guard for the other overlays. Truncation itself is unchanged, whether long messages should wrap instead is a separate question.
