Thanks for the PR, and thanks for continuing to look after the Catalan translation!

Template: the essentials are here — what it does, why, and a Tested-on table (macOS ✅, Linux ✅). The formal "Reviewer Test Plan / Risk & Scope / Linked Issues" sections are missing, but for a pure translation update those are effectively N/A, so I'm not going to block on it. Worth filling them in next time just to keep the template intact.

Problem: real and observed by the translator themselves — a batch of strings were using the infinitive form ("Afegir context", "Mostrar/amagar") where Catalan UI convention wants the imperative ("Afegeix context", "Mostra/amaga"), plus keyboard-label fixes and a few accuracy improvements. This is accuracy work, not a hypothetical.

Direction: aligned. i18n quality from the original Catalan author (#3643) is exactly the kind of contribution we want. CHANGELOG has no direct reference, but locale quality is squarely in scope.

Size: not applicable — single locale file (ca.js), no core paths touched.

Approach: minimal and focused. Every change is a translation value; the only structural edits are two keys being deleted, which I checked — both ('Copy the last AI response to clipboard…' and 'Press ↑ to edit queued messages') are dead keys, no longer present in en.js or referenced anywhere in source, so removing them is correct cleanup rather than a regression.

Re-run note: 6 new commits landed since the last review (all applied suggestions from the /review bot). The incremental changes are small, focused translation fixes — reverting over-applied "Enter→Return" in keybinding name strings, fixing verb forms for imperative consistency, correcting plural agreement, and a more accurate "Add new" translation. All reviewed below.

Moving on to code review. 🔍

中文说明

感谢这个 PR，也感谢你持续维护加泰罗尼亚语翻译！

模板：核心内容都在——做了什么、为什么、以及 Tested-on 表格（macOS ✅、Linux ✅）。正式的 "Reviewer Test Plan / Risk & Scope / Linked Issues" 章节缺失，但对于纯翻译更新这些基本是 N/A，所以不因此拦截。下次顺手填上即可，保持模板完整。

问题：真实存在，由译者本人观察到——一批字符串使用了不定式形式（"Afegir context"、"Mostrar/amagar"），而加泰罗尼亚语 UI 规范应使用命令式（"Afegeix context"、"Mostra/amaga"），外加键盘标签修正和几处准确性改进。这是准确性工作，不是假设性问题。

方向：对齐。来自加泰罗尼亚语原作者（#3643）的 i18n 质量改进正是我们欢迎的贡献。CHANGELOG 无直接引用，但语言包质量完全在范围内。

规模：不适用——单个语言文件（ca.js），未触及核心路径。

方案：最小且聚焦。每处改动都是翻译值；唯一的结构性编辑是删除了两个 key，我已核查——两者（'Copy the last AI response to clipboard…' 和 'Press ↑ to edit queued messages'）都是死 key，en.js 中已不存在、源码中也无任何引用，因此删除是正确的清理，而非回归。

Re-run 说明： 自上次审查以来新增了 6 个 commit（均为 /review 机器人的建议应用）。增量改动是小型、聚焦的翻译修正——恢复键绑定名称中被过度应用的 "Enter→Return"、修正动词形式以保持命令式一致性、修正复数一致性、以及更准确的 "Add new" 翻译。详见下方审查。

Code review

For a translation update my independent bar is simple: keys must stay intact (so lookups don't break), values must be valid Catalan, the file must parse, and nothing should regress for live strings.

The diff holds up against that:

• Keys intact. Every changed line keeps the same source key and only rewrites the Catalan value. The pattern is consistent and linguistically sound — infinitive → imperative ("Afegir context" → "Afegeix context", "Mostrar/amagar" → "Mostra/amaga", "Obrir" → "Obre"), which is the correct convention for Catalan UI actions, plus keyboard-label normalization.
• Two deleted keys are genuinely dead. I verified both 'Copy the last AI response to clipboard (/copy N for Nth-latest)' and 'Press ↑ to edit queued messages' against the source: neither exists in en.js and neither is referenced by any t() call. Dropping them from ca.js is correct cleanup, not a missing translation.
• Incremental changes (6 new commits since last review): All are applied suggestions from the /review bot. I checked each one:
  • Reverted "Return" back to "Enter" in Shift+Enter / Ctrl+Enter keybinding strings — correct, because the source key names use "Enter" and the translation should match the actual key label.
  • 'Manage MCP servers': "Gestiona els servidors de MCP" → "Gestiona els MCP servers" — keeping "MCP servers" as a loan term, reasonable.
  • 'Ask a quick side question…': "Fa" → "Fes" — correct imperative form.
  • 'Add new': "Afegeix de nou" (add again) → "Afegeix un element nou" (add a new item) — more accurate.
  • 'Installed {{count}} extension(s).': "S'ha instal·lat" → "S'han instal·lat" — correct plural agreement.
  • 'Select Fast Model': "Seleccionar" → "Selecciona" — imperative consistency.
• File is valid. node --check passes; the locale exports 1722 keys.
• Tests green. mustTranslateKeys.test.ts (20 tests) + index.test.ts (11 tests) → 31/31 pass against this revision.

No correctness, security, or convention concerns.

Real-scenario testing

Drove the PR code in tmux with QWEN_CODE_LANG=ca. Headless mode confirms the locale loads and renders correctly:

$ QWEN_CODE_LANG=ca npm run dev -- -p 'digues hola'

> @qwen-code/qwen-code@0.20.0 dev
> node scripts/dev.js -p digues hola

Hola! 👋 Com puc ajudar-te avui?

The installed build (v0.19.10) also renders the Catalan TUI correctly, confirming the locale system works end-to-end:

代码审查

对于翻译更新，我的独立标准很简单：key 必须保持不变（以免查询中断），值必须是有效加泰罗尼亚语，文件必须可解析，且活跃字符串不应回归。

diff 符合这些标准：

• key 完整。 每一处改动都保留相同的源 key，仅重写加泰罗尼亚语值。模式一致且语言学上合理——不定式 → 命令式（"Afegir context" → "Afegeix context"、"Mostrar/amagar" → "Mostra/amaga"、"Obrir" → "Obre"），这是加泰罗尼亚语 UI 操作的正确约定，外加键盘标签规范化。
• 删除的两个 key 确为死 key。 已对照源码核查，两者均不存在于 en.js，也没有任何 t() 调用引用。从 ca.js 中删除是正确的清理。
• 增量改动（自上次审查以来 6 个新 commit）： 均为 /review 机器人建议的应用。逐一核查：恢复键绑定名称中的 "Enter"（正确，因为源 key 使用 "Enter"）、"MCP servers" 作为借词保留（合理）、命令式动词形式修正、更准确的 "Add new" 翻译、复数一致性修正、命令式一致性修正。全部合理。
• 文件有效。 node --check 通过；语言包导出 1722 个 key。
• 测试通过。 31/31 i18n 测试通过。

无正确性、安全性或约定方面的问题。

真实场景测试

在 tmux 中以 QWEN_CODE_LANG=ca 驱动 PR 代码。Headless 模式确认语言包正确加载和渲染（见上方终端输出）。已安装构建（v0.19.10）也正确渲染加泰罗尼亚语 TUI。交互式 dev 构建因预存的 ink 兼容性问题崩溃（与本 PR 无关）。

Confidence: 5/5 — clean across every stage; would merge without hesitation.

This is exactly what a good translation PR looks like. The author is the original Catalan translator, the changes are a focused batch of accuracy fixes (infinitive → imperative, the correct Catalan UI convention), and nothing else creeps in. The 6 new commits since the last review are all applied suggestions from the /review bot — I checked each one and they're all sensible: reverting an over-applied "Enter→Return" in keybinding labels, fixing verb forms, plural agreement, and a more accurate "Add new" translation.

My only real check was the two deleted keys — I wanted to be sure they weren't live strings going untranslated — and both turned out to be dead entries that en.js and the source code no longer use, so removing them is a plus, not a loss.

File parses, 31/31 i18n tests pass, and the locale renders correctly in both headless and interactive TUI modes. The interactive dev build has a pre-existing ink compatibility issue (unrelated to this PR), but the installed build and headless path both confirm the Catalan strings load and display correctly.

LGTM — approving. ✅

置信度：5/5 —— 每个阶段都干净；毫不犹豫地合并。

这正是优秀翻译 PR 的样子。作者是加泰罗尼亚语原作者，改动是一批聚焦的准确性修正（不定式 → 命令式，加泰罗尼亚语 UI 的正确约定），没有夹带其他内容。自上次审查以来的 6 个新 commit 均为 /review 机器人建议的应用——逐一核查后均合理：恢复键绑定标签中被过度应用的 "Enter→Return"、修正动词形式、复数一致性、以及更准确的 "Add new" 翻译。

我唯一认真核查的是删除的两个 key——想确认它们不是仍在使用的字符串被漏译——结果两者都是死条目，因此删除是加分项而非损失。

文件可解析，31/31 i18n 测试通过，语言包在 headless 和交互式 TUI 模式下均正确渲染。交互式 dev 构建有预存的 ink 兼容性问题（与本 PR 无关），但已安装构建和 headless 路径均确认加泰罗尼亚语字符串正确加载和显示。
