VooDisss 2c27fc53ad perf(ui): fix O(n²) in liveSegmentChars and selectedTokenTotal, add i18n + SSR guard
Addresses bot review feedback on commit 224cab6.

## Performance: liveSegmentChars O(n²) → O(n)

The memo had three inner loops scanning all props.segments per unique
messageId. Added a single O(n) pre-pass building a
segmentsByMessageId Map, then replaced all three inner loops with
map lookups. Total complexity: O(n) instead of O(m×n).

File: packages/ui/src/components/message-timeline.tsx

## Performance: selectedTokenTotal O(n²) → O(n)

For each selected messageId, the memo scanned all segments to sum
chars. On "Select all" this was O(selected × segments). Now builds a
charsByMessageId map in one O(n) pass and does O(1) lookups per
selected message. Same pattern as aggregateTokensByMessageId.

## SSR guard: resize listener

window.addEventListener("resize", computeBadgeLayout) lacked a
typeof window !== "undefined" guard. Other window usage in the file
was guarded. Wrapped the addEventListener, requestAnimationFrame, and
onCleanup block in the guard.

File: packages/ui/src/components/message-timeline.tsx

## i18n: mirror selectionHint key in 5 locale files

messageSection.bulkDelete.selectionHint was only defined in
en/messaging.ts. Added the key (English string, since Ctrl/Shift/Esc
are universal keyboard labels) to es, fr, ja, ru, and zh-Hans.

CodeNomad UI

This package contains the frontend user interface for CodeNomad, built with SolidJS and Tailwind CSS.

Overview

The UI is designed to be a high-performance, low-latency cockpit for managing OpenCode sessions. It connects to the CodeNomad server (either running locally via CLI or embedded in the Electron app).

Features

  • SolidJS: Fine-grained reactivity for high performance.
  • Tailwind CSS: Utility-first styling for rapid development.
  • Vite: Fast build tool and dev server.

Development

To run the UI in standalone mode (connected to a running server):

npm run dev

This starts the Vite dev server at http://localhost:3000.

Building

To build the production assets:

npm run build

The output will be generated in the dist directory, which is then consumed by the Server or Electron app.

Debug Logging

The UI now routes all logging through a lightweight wrapper around debug. The logger exposes four namespaces that can be toggled at runtime:

  • sse Server-sent event transport and handlers
  • api HTTP/API calls and workspace lifecycle
  • session Session/model state, prompt handling, tool calls
  • actions User-driven interactions in UI components

You can enable or disable namespaces from DevTools (in dev or production builds) via the global window.codenomadLogger helpers:

window.codenomadLogger?.listLoggerNamespaces() // => [{ name: "sse", enabled: false }, ...]
window.codenomadLogger?.enableLogger("sse") // turn on SSE logs
window.codenomadLogger?.disableLogger("sse") // turn them off again
window.codenomadLogger?.enableAllLoggers() // optional helper

Enabled namespaces are persisted in localStorage under opencode:logger:namespaces, so your preference survives reloads.
