Enable PDF files to be previewed directly in the file content panel
instead of showing as unsupported files requiring download. Uses the
existing react-pdf-highlighter library with zoom controls and keyboard
shortcuts (up/down arrows).
Add a unified isPreviewable flag to useFileTypeInfo that guards against
rendering binary files as text in both skill artifacts and variable
inspect artifacts preview. Upgrade extension arrays to Sets for O(1)
lookups.
Backend returns extensions with a leading dot (e.g., `.png` from
`os.path.splitext`), causing binary/media files to be misclassified
as text since they didn't match the dot-free extension lists.
Enhance getFileIconType to accept an extension parameter and cover all
13 FileAppearanceTypeEnum types using an O(1) Map lookup. Update all
call sites to pass the API-provided extension for accurate icon display.
Switch from whitelist to blacklist pattern for determining editable files.
Files are now editable unless they are known binary types (audio, archives,
executables, Office documents, fonts, etc.), enabling support for any
runtime-generated text files without needing to add extensions one by one.
Remove the Office file placeholder that only showed "Preview will be
supported in a future update" without any download option. Office files
(pdf, doc, docx, xls, xlsx, ppt, pptx) now fall through to the generic
"unsupported file" handler which provides a download button.
Removed:
- OfficeFilePlaceholder component
- isOfficeFile function and OFFICE_EXTENSIONS constant
- isOffice flag from useFileTypeInfo hook
- i18n keys for officePlaceholder
This simplifies the file type handling to just three categories:
- Editable: markdown, code, text files → editor
- Previewable: image, video files → media preview
- Everything else: download button
- Extract useFileOperations hook to hooks/use-file-operations.ts
- Move tree utilities to utils/tree-utils.ts
- Move file utilities to utils/file-utils.ts (renamed from utils.ts)
- Remove unnecessary JSDoc comments throughout components
- Simplify type.ts to only contain local type definitions
- Clean up store/index.ts by removing verbose comments
