feat: sync workspace trust setting from vscode

[zhangtony239]

Context

Enable Roo's workspace-related features only when vscode is in workspace mode, in order to reduce visual and usability overhead for users who are not accustomed to using workspaces.

Screenshots

before (workspace enabled)	after (workspace disabled)

How to Test

• Run this code.
• Switch VS Code’s workspace setting (make sure to save your data first, as this will immediately restart VS Code).
• Check the Home and History pages. Workspace-related content should no longer be visible when VS Code is not in workspace mode — the UI should resemble how Roo looked before workspace support was added.

Important

Syncs VSCode's workspace trust setting to control workspace-related UI and functionality in the application.

• Behavior:
  • Syncs workspace.trust.enabled setting from VSCode in ClineProvider.
  • Updates UI in HistoryPreview.tsx and HistoryView.tsx to hide workspace-related content if workspace trust is disabled.
• State Management:
  • Adds workspaceTrustEnabled to ExtensionState in ExtensionMessage.ts and ExtensionStateContext.tsx.
  • Uses useEffect in HistoryPreview.tsx and HistoryView.tsx to set showAllWorkspaces based on workspaceTrustEnabled.
• Misc:
  • Updates getStateToPostToWebview() in ClineProvider.ts to include workspaceTrustEnabled.

Thanks @zhangtony239! @samhvw8 mind taking a look at this one to see if it looks ok to you?

@zhangtony239 @mrubens can we add more information like "History Is Filtered Because Workspace Not Trusted" something like that for UI UX ?

[zhangtony239]

Well... as more UI elements are added in the future, it's foreseeable that the Interface section in settings will need a more detailed level of personalization, which allowing users to achieve true visual efficiency in their day-to-day use of Roo. The implementation in this PR should actually be considered part of that — specifically, it's the effect you'd expect when the Workspace toggle is enabled under the auto option.

No doubt this would make Roo way more flexible for different user preferences — but it also means quite a bit of extra work... so, curious to hear your thoughts! @mrubens @samhvw8

@zhangtony239 @mrubens can we add more information like "History Is Filtered Because Workspace Not Trusted" something like that for UI UX ?

And this could be added in the description of those settings.

[zhangtony239]

Given the limitations in the current implementation and the fact that it's fallen behind the latest changes, I'm closing this PR for now.
I really appreciate the discussion and feedback from everyone — I'll revisit and rework this in a cleaner way when possible.
