feat: add korean localization toggle

[gracefully91]

한글화 해봤습니다~~

설정에 언어 선택 버튼도 넣었는데 확인해보세유~~

Thanks for the Korean localization work @gracefully91 — the translations are natural and well done!

However, requesting changes before this can be merged:

Bug

• Duplicate span in SetupWizard.tsx: The original English "Custom ports" <span> is left in alongside the new translated <span>, so both render side by side. The original should be replaced, not duplicated.

Code quality

• Inline ternary pattern doesn't scale. Currently every string uses locale === "ko" ? "한글" : "English" directly in JSX — this is repeated hundreds of times across 18 files. Your own SettingsPage.tsx already uses a much cleaner dictionary (COPY) pattern. Could you refactor the other components to use the same approach? For example:

// Per-component or shared dictionary
const COPY = {
  en: { title: "Settings", save: "Save" },
  ko: { title: "설정", save: "저장" },
};
const t = COPY[locale];

// Then in JSX:
<h1>{t.title}</h1>

This keeps components readable and makes adding a third language trivial.

Minor

• \n- in the welcome message headline ("QuadWork에 오신 걸 환영합니다\n- 첫 AI 개발 팀을 설정해볼까요") looks like a formatting artifact.

Happy to merge once these are addressed!

Hi @realproject7! I've addressed all three points:

Bug — Removed the duplicate for "Custom ports" in SetupWizard.tsx
Code quality — Refactored all 16 components to use the per-component COPY dictionary pattern (matching SettingsPage.tsx)
Minor — Fixed the \n- artifact → restored as \n— to preserve the intended line break

Ready for re-review! 🍊

[realproject7]

Thanks for addressing the duplicate span and the \n- artifact — both are fixed!

The COPY dictionary refactor is partially done but 49 inline locale === "ko" ternaries still remain in JSX across 17 files. These need to be moved into the COPY dictionaries for consistency and maintainability.

What needs to change

Rule: Every user-visible string must live in the COPY dictionary

No inline ternaries in JSX. Every locale === "ko" ? "한글" : "English" in rendering code should be replaced by a COPY key. The only place locale should appear in a component is:

const { locale } = useLocale();
const t = COPY[locale];

After that, JSX should only reference t.someKey — never locale directly.

How to handle strings with interpolation

Some inline ternaries were left because the string contains dynamic values like ${count}. Use a function in the COPY dictionary:

// ❌ Current (inline ternary with interpolation)
<span>{locale === "ko" ? `${count}개 항목` : `${count} items`}</span>

// ✅ Correct (function in COPY)
const COPY = {
  en: {
    itemCount: (n: number) => `${n} items`,
  },
  ko: {
    itemCount: (n: number) => `${n}개 항목`,
  },
};

// In JSX:
<span>{t.itemCount(count)}</span>

How to handle JSX elements inside translated strings

For strings that contain inline <code>, <strong>, etc., split the COPY entry into parts:

// ❌ Current (fragile string split)
t.cleanupIntro.split("~/.quadwork/{id}/agentchattr")

// ✅ Correct (structured COPY entries)
const COPY = {
  en: {
    cleanupBefore: "Per-project clones are necessary so multiple projects can run AgentChattr simultaneously without port conflicts. Existing v1 users are auto-migrated to per-project clones on the next ",
    cleanupCode: "~/.quadwork/{id}/agentchattr",
    cleanupAfter: "; once every project has a working clone, the legacy shared install can be removed safely via ",
  },
  ko: {
    cleanupBefore: "프로젝트별 클론은 ...",
    cleanupCode: "~/.quadwork/{id}/agentchattr",
    cleanupAfter: "; 모든 프로젝트에 ...",
  },
};

// In JSX:
<p>{t.cleanupBefore}<code>{t.cleanupCode}</code>{t.cleanupAfter}</p>

---

Files with remaining inline ternaries (all must be fixed)

High priority (many ternaries)

1. SetupWizard.tsx — 13 inline ternaries

   • getInitialSteps() function has 12 ternaries for step labels and subtitles. Move all step label and subtitle strings into COPY:

     // ❌ Current
     { label: locale === "ko" ? "필수 도구" : "Prerequisites", subtitle: locale === "ko" ? "필수 도구 확인" : "Check required tools" }
     
     // ✅ Move to COPY
     const COPY = {
       en: {
         stepPrereqLabel: "Prerequisites",
         stepPrereqSubtitle: "Check required tools",
         // ... all other steps
       },
       ko: {
         stepPrereqLabel: "필수 도구",
         stepPrereqSubtitle: "필수 도구 확인",
       },
     };
     
     // Then:
     { label: t.stepPrereqLabel, subtitle: t.stepPrereqSubtitle }

   • Also fix the remaining JSX ternaries ("auto-detected", "no local clone found", branch protection text)

2. GitHubPanel.tsx — 7 inline ternaries

   • Rate limit messages, Issues/PRs headers with counts, tooltip bodies
   • Use function pattern for count interpolations: issuesHeader: (n: number) => \ISSUES (${n})``

3. BatchProgressPanel.tsx — 5 inline ternaries

   • Batch number display, items count, tooltip text

4. HomeDashboard.tsx — 5 inline ternaries

   • Project count display
   • timeAgo() function has 4 ternaries for time units — move all into COPY as functions: minutesAgo: (n: number) => \${n}분 전``

Medium priority (1-2 ternaries each)

5. ControlBar.tsx — 2 (tooltip help text for Keep Mac Awake and Notification Sound)
6. AgentModelsWidget.tsx — 1-2
7. AgentTerminalsGrid.tsx — 1-2
8. DiscordBridgeWidget.tsx — 1-2
9. TelegramBridgeWidget.tsx — 1-2
10. LoopGuardWidget.tsx — 1-2
11. OperatorFeaturesPanel.tsx — 1-2
12. ProjectDashboard.tsx — 1-2
13. ProjectHistoryWidget.tsx — 1-2
14. ScheduledTriggerWidget.tsx — 1-2

For all of these: move the remaining tooltip bodies and dynamic labels into each file's COPY dictionary.

---

Other fixes needed

1. Remove unnecessary type casts in SetupWizard.tsx — locale as "en" | "ko" is redundant since useLocale() already returns Locale which is "en" | "ko". Just use COPY[locale] directly.

2. SettingsPage.tsx cleanup text — replace the fragile .split("~/.quadwork/{id}/agentchattr") approach with structured COPY entries (see example above).

---

Checklist before re-requesting review

• Zero locale === "ko" ternaries remain in any JSX/rendering code
• All user-visible strings live in COPY dictionaries
• Strings with dynamic values use function entries in COPY
• Strings with JSX elements use structured COPY entries (before/after pattern)
• No as "en" | "ko" type casts
• npm run build passes cleanly

[gracefully91]

All 49 inline locale === "ko" ternaries have been moved into COPY dictionaries across all 17 files.

Removed the as "en" | "ko" type casts and replaced the .split() pattern in SettingsPage with structured before/code/after entries.

Thanks for the detailed breakdown!

Hi @gracefully91! The localization work looks great — translations are natural and the COPY dictionary refactor is clean. Two things needed before we can merge:

---

1. Rebase on current main (critical)

Your fork is based on an older main. Since you opened this PR, we've merged 10+ PRs (security fixes, AC crash recovery, init/launch separation, etc.). Your branch currently carries reverse diffs to server files (server/index.js, bin/quadwork.js, server/routes.js, etc.) that would revert critical fixes if merged.

Git shows no merge conflicts, but that makes it worse — the reverts would happen silently.

Please rebase your branch on the latest main:

# Add the upstream remote (if not already)
git remote add upstream https://github.com/realproject7/quadwork.git

# Fetch latest
git fetch upstream main

# Rebase your branch
git rebase upstream/main

# Force-push to update the PR
git push --force-with-lease origin main

After rebasing, the diff should only show changes in src/, src/lib/locale.ts, and src/app/globals.css — no changes to server/, bin/, scripts/, or package.json.

2. Remove unused COPY keys in SettingsPage.tsx

These 4 keys are defined but never used in JSX (the function versions onlyInstalledMsg / installOtherMsg replaced them):

onlyInstalledPrefix
onlyInstalledSuffix
installOther
forMoreBackendOptions

Remove them from both the en and ko objects in SettingsPage.tsx's COPY dictionary.

3. Verify build

After rebasing, please confirm npm run build passes cleanly.

---

That's it! Once rebased and cleaned up, we're ready to merge. Thanks for the thorough work on this 🙏

Good Night @realproject7!

I’ve updated the PR to address all your feedback:

1. Rebase complete: I've rebased the branch onto the latest upstream/main.
   The diff now correctly shows changes only in src/,
   src/lib/locale.ts, and src/app/globals.css. All reverse diffs to the server and bin files have been cleared.

2. Cleanup: Removed the 4 unused COPY keys (onlyInstalledPrefix, onlyInstalledSuffix, installOther,
   forMoreBackendOptions) from SettingsPage.tsx.
   I also refactored the CLI installation message to use the oneCliInstalled key and a cleaner localization logic.

3. Refined Translations: Polished several Korean strings (especially the @Head instructions in the help modal)
   to make them more natural.

4. Verified Build: Confirmed that npm run build passes cleanly without any type errors.

Everything should be ready for review now. Thanks! 🙏
