TASK-035: remove redundant per-file Commit button from the code browser

The header's 'Commit' button (onViewHistory) just switched
BranchDetailScreen's pager to page 1 -- the exact same action the
top-level 'Commit' tab's own onClick already performs. No path/file
info ever flowed through it, so it was never actually file-specific
history, just a duplicate shortcut that TASK-031's rename made obvious.
Removed the button, its parameter threading, and the now-unused
codebrowser_history string.

+## 2026-08-29 (continued) — TASK-035: remove the redundant per-file "커밋" button in the code browser
+
+- Agent and role: Claude, direct continuation of the same live session — "현재 보고있는 페이지 우상단에 커밋 버튼은 이제 필요 없지 않나" (the Commit button in the top-right of the current page isn't needed anymore, is it).
+- Commit/diff: on `claude/task-015-notifications`; `feature/codebrowser/CodeBrowserScreen.kt`, `feature/branchdetail/BranchDetailScreen.kt`, `strings_codebrowser.xml`, `tasks/035-remove-redundant-code-browser-commit-button.md`.
+- Confirmed the observation was correct before acting on it: traced the header's "커밋" button (`onViewHistory`) all the way to its single call site in `BranchDetailScreen.kt` and found it just switched the pager to page 1 — the exact same action the top-level "커밋" tab's own `onClick` already performs a few lines above it. TASK-031's rename (both controls used to be independently labeled "히스토리"/differently-purposed before that) is what made the duplication visually obvious.
+- How it was implemented: removed the button and the `onViewHistory` parameter threaded through `CodeBrowserScreen`/`BrowserHeader`, the call site in `BranchDetailScreen.kt`, and the now-unused `codebrowser_history` string resource (confirmed unused via a repo-wide search first). `BrowserHeader`'s title/ref layout simplified from a `Row`-wrapped `Column` to a plain `Column` now that there's no trailing button to share the row with. Also fixed a stale "History" word in a doc comment one line above (predating TASK-031's rename).
+- Files changed: `CodeBrowserScreen.kt`, `BranchDetailScreen.kt`, `strings_codebrowser.xml`, `tasks/035-remove-redundant-code-browser-commit-button.md`.
+- Checks and results: `./gradlew compileDebugKotlin compileDebugUnitTestKotlin testDebugUnitTest assembleDebug lintDebug` BUILD SUCCESSFUL, all unit tests passing, 0 lint errors. Installed on the human product owner's device over wireless `adb`.
+- Review findings and resolutions: None from a separate review pass.
+- Known limitations: None identified.
+- Next recommended task: get live confirmation the header looks right without the button; otherwise continue per the standing direction on the rest of this session's queued items.
+- Next owner: Claude, continuing per the standing direction.

+# TASK-035: Remove the redundant per-file "커밋" button in the code browser
+
+Status: implemented; all required checks pass; live-installed, awaiting the human product owner's confirmation
+Owner: Claude
+Reviewer: Codex
+
+## Outcome
+
+Live-reported: "현재 보고있는 페이지 우상단에 커밋 버튼은 이제 필요 없지 않나" (the Commit button
+in the top-right of the current page isn't needed anymore, is it). Confirmed correct: the code
+browser's header showed an `OutlinedButton` (originally labeled "히스토리", renamed to "커밋" by
+TASK-031) that just switched `BranchDetailScreen`'s pager to page 1 — the exact same destination
+the top-level "커밋" tab (also renamed by TASK-031) already switches to with one tap, with no
+file-specific filtering or other distinct behavior. Since TASK-031 gave both controls the identical
+label doing the identical thing, the in-content button became pure duplication. Removed it.
+
+## Scope
+
+- Included: `feature/codebrowser/CodeBrowserScreen.kt` (`BrowserHeader`'s button and the
+  `onViewHistory` parameter threaded through `CodeBrowserScreen`), `feature/branchdetail/BranchDetailScreen.kt`
+  (the call site, plus a doc-comment word fix from a prior rename), `strings_codebrowser.xml`
+  (removed the now-unused `codebrowser_history` string).
+- Excluded: The top-level "커밋" tab and `HistoryScreen` itself are untouched — this removes only
+  the duplicate shortcut, not the feature it duplicated. No change to any other button or gesture
+  in the code browser.
+
+## Design notes
+
+- **Confirmed it was truly redundant before removing it, not just probably**: traced
+  `onViewHistory` all the way from `BrowserHeader`'s button through `CodeBrowserScreen`'s parameter
+  to its one call site in `BranchDetailScreen.kt` —
+  `onViewHistory = { scope.launch { pagerState.animateScrollToPage(1) } }` — which is exactly the
+  same action the "커밋" `Tab`'s own `onClick` performs a few lines above it. No path/file
+  information ever flowed through `onViewHistory`, so this was never actually "view this specific
+  file's history," despite once being labeled that way before TASK-031's rename made the
+  duplication obvious.
+- **Header simplified along with the removal**: `BrowserHeader`'s title/ref `Column` no longer
+  needs to share a `Row` with a trailing button, so it collapsed back to a plain `Column` — one
+  less nested layout, not just a deleted button.
+
+## Acceptance criteria
+
+- [x] The code browser's header (shown across Loading/Directory/File/UnsupportedEntry/Error states)
+      no longer shows a "커밋" button.
+- [x] The top-level "커밋" tab in `BranchDetailScreen` is unaffected and remains the only way to
+      reach commit history from this screen.
+- [x] No leftover references to `onViewHistory` or the removed `codebrowser_history` string
+      resource anywhere in the app.
+- [x] Build, unit tests, and lint pass.
+- [ ] Live confirmation from the human product owner that the header now looks right without it —
+      installed on the device but not yet re-viewed in this exact session.
+
+## Required checks
+
+```text
+./gradlew compileDebugKotlin compileDebugUnitTestKotlin
+./gradlew testDebugUnitTest
+./gradlew assembleDebug lintDebug
+```
+
+## Evidence
+
+- `CodeBrowserScreen.kt`: `onViewHistory` parameter removed from `CodeBrowserScreen` and
+  `BrowserHeader`; the `OutlinedButton` removed; `BrowserHeader`'s title/ref layout simplified from
+  a `Row`-wrapped `Column` to a plain `Column`.
+- `BranchDetailScreen.kt`: the `onViewHistory = { ... }` argument removed from the one
+  `CodeBrowserScreen(...)` call site; a stale doc-comment reference to "History" (predating
+  TASK-031's tab rename) corrected to "Commit".
+- `strings_codebrowser.xml`: `codebrowser_history` string removed (confirmed unused via a
+  repository-wide search before deleting it).
+- `./gradlew compileDebugKotlin compileDebugUnitTestKotlin`: BUILD SUCCESSFUL.
+- `./gradlew testDebugUnitTest`: BUILD SUCCESSFUL, all unit tests passing (no test referenced the
+  removed button/parameter/string).
+- `./gradlew assembleDebug lintDebug`: BUILD SUCCESSFUL, 0 lint errors.
+- Installed on the human product owner's device over wireless `adb` (`adb install -r`, streamed
+  install succeeded); not yet re-viewed live in this exact session.
+
+## Known limitations
+
+None identified.
+
+## Review findings
+
+None yet — pending Codex/human review.
