Fix .docx file crash

[keikari]

This was crashing, due to DocxViewer only being imported on the desktop App.
But importing it on web doesn't seem to work.
This change defaults .docx to render in the Download only view

Summary by CodeRabbit

• Chores
  • DOCX file handling/rendering is now limited to the app build only. This reduces unnecessary docx-related logic in non-app distributions, streamlines builds, and can help reduce bundle size and potential edge-case behavior outside the app. No public APIs or exported signatures were changed.

📝 Walkthrough

Walkthrough

A preprocessor-style conditional was added around the DOCX render-mode branch in a content selector, enclosing the existing docx-handling logic with app-only markers so that this code path is excluded from non-app builds. No functional logic was changed.

Changes

Cohort / File(s)	Summary
Build Conditionals ui/redux/selectors/content.js	Wrapped the DOCX (extension === 'docx') render-mode branches with app-only conditional markers: // @if TARGET='app' ... // @endif``, excluding that branch from non-app builds. No other logic changes.

Poem

🐰 I tucked the DOCX path behind a gate,
Only app builds now may navigate,
Two tiny markers, tidy and neat,
Keep the branches well discrete. ✨

296-298: ⚠️ Potential issue | 🔴 Critical

Add missing // @if TARGET='app' guard around the docx check in selectFileRenderModeForUri.

The docx check in selectFileRenderModeForUri (lines 296–298) lacks the // @if TARGET='app' guard that exists in the equivalent makeSelectFileRenderModeForUri selector. While selectFileRenderModeForUri is not directly used in the codebase, it powers selectIsPlayableForUri which is called from content.js actions that execute on all builds, allowing unguarded DOCX rendering on web and triggering the crash this PR aims to fix.

Proposed fix

     if (['text', 'document', 'script'].includes(mediaType)) {
       return RENDER_MODES.DOCUMENT;
     }
+    // `@if` TARGET='app'
     if (extension === 'docx') {
       return RENDER_MODES.DOCX;
     }
+    // `@endif`
