# Description of Changes
Because we used string typing for IDs and names, it was really easy to
make mistakes where variables named like `subcategory` would be stored
as an ID in one file, but then read assuming it's a name in another
file. This PR changes the code to consistently use enum cases when
referring to IDs of categories, subcategories, and tools (at least in as
many places as I can find them, ~I had to add a `ToolId` enum for this
work~ I originally added a `ToolId` type for this work, but it caused
too many issues when merging with #4222 so I've pulled it back out for
now).
Making that change made it obvious where we were inconsistently passing
IDs and reading them as names etc. allowing me to fix rendering issues
in the All Tools pane, where the subcategory IDs were being rendered
directly (instead of being translated) or where IDs were being
translated into names, but were then being re-translated, causing
warnings in the log.
Component Extraction & Context Refactor - Summary
🔧 What We Did
- Extracted HomePage's 286-line monolithic component into focused parts
- Created ToolPanel (105 lines) for tool selection UI
- Created Workbench (203 lines) for view management
- Created ToolWorkflowContext (220 lines) for centralized state
- Reduced HomePage to 60 lines of provider setup
- Eliminated all prop drilling - components use contexts directly
🏆 Why This is Good
- Maintainability: Each component has single purpose, easy
debugging/development
- Architecture: Clean separation of concerns, future features easier to
add
- Code Quality: 105% more lines but organized/purposeful vs tangled
spaghetti code

# Description of Changes
This pull request introduces significant updates to the file selection
logic, tool rendering, and file context management in the frontend
codebase. The changes aim to improve modularity, enhance
maintainability, and streamline the handling of file-related operations.
Key updates include the introduction of a new `FileSelectionContext`,
refactoring of file selection logic, and updates to tool management and
rendering.
### File Selection Context and Logic Refactor:
* Added a new `FileSelectionContext` to centralize file selection state
and provide utility hooks for managing selected files, selection limits,
and tool mode. (`frontend/src/contexts/FileSelectionContext.tsx`,
[frontend/src/contexts/FileSelectionContext.tsxR1-R77](diffhunk://#diff-bda35f1aaa5eafa0a0dc48e0b1270d862f6da360ba1241234e891f0ca8907327R1-R77))
* Replaced local file selection logic in `FileEditor` with context-based
logic, improving consistency and reducing duplication.
(`frontend/src/components/fileEditor/FileEditor.tsx`,
[[1]](diffhunk://#diff-481d0a2d8a1714d34d21181db63a020b08dfccfbfa80bf47ac9af382dff25310R63-R70)
[[2]](diffhunk://#diff-481d0a2d8a1714d34d21181db63a020b08dfccfbfa80bf47ac9af382dff25310R404-R438)
### Tool Management and Rendering:
* Refactored `ToolRenderer` to use a `Suspense` fallback for lazy-loaded
tools, improving user experience during tool loading.
(`frontend/src/components/tools/ToolRenderer.tsx`,
[frontend/src/components/tools/ToolRenderer.tsxL32-L64](diffhunk://#diff-2083701113aa92cd1f5ce1b4b52cc233858e31ed7bcf39c5bfb1bcc34e99b6a9L32-L64))
* Simplified `ToolPicker` by reusing the `ToolRegistry` type, reducing
redundancy. (`frontend/src/components/tools/ToolPicker.tsx`,
[frontend/src/components/tools/ToolPicker.tsxL4-R4](diffhunk://#diff-e47deca9132018344c159925f1264794acdd57f4b65e582eb9b2a4ea69ec126dL4-R4))
### File Context Enhancements:
* Introduced a utility function `getFileId` for consistent file ID
extraction, replacing repetitive inline logic.
(`frontend/src/contexts/FileContext.tsx`,
[[1]](diffhunk://#diff-95b3d103fa434f81fdae55f2ea14eda705f0def45a0f2c5754f81de6f2fd93bcR25)

* Updated `FileContextProvider` to use more specific types for PDF
documents, enhancing type safety.
(`frontend/src/contexts/FileContext.tsx`,
[[1]](diffhunk://#diff-95b3d103fa434f81fdae55f2ea14eda705f0def45a0f2c5754f81de6f2fd93bcL350-R351)

### Compression Tool Enhancements:
* Added blob URL cleanup logic to the compression hook to prevent memory
leaks. (`frontend/src/hooks/tools/compress/useCompressOperation.ts`,
[frontend/src/hooks/tools/compress/useCompressOperation.tsR58-L66](diffhunk://#diff-d7815fea0e89989511ae1786f7031cba492b9f2db39b7ade92d9736d1bd4b673R58-L66))
* Adjusted file ID generation in the compression operation to handle
multiple files more effectively.
(`frontend/src/hooks/tools/compress/useCompressOperation.ts`,
[frontend/src/hooks/tools/compress/useCompressOperation.tsL90-R102](diffhunk://#diff-d7815fea0e89989511ae1786f7031cba492b9f2db39b7ade92d9736d1bd4b673L90-R102))
