# 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))
