[Feat] Add Roo Code history import to the About page

[roomote]

Opened on behalf of Toray Altas. View the task or mention @roomote for follow-up asks.

What problem this solves

Adds a clearer Roo Code history import flow in Zoo Code's About page so users can bring over existing task history and see visible progress while the import is running.

Why this change was made

The import flow already resolved Roo and Zoo storage roots and copied only the top-level history files Zoo uses. This update threads progress events from the extension host back to the About card, so the UI can disable the action while the import is active and show real percentage/file progress instead of looking idle.

User impact

Users now get a more obvious Import history from Roo Code card in the About section, plus a live progress bar, percentage, and copy counts while Roo history is being imported. When the import finishes, Zoo refreshes the history list immediately; when there is nothing to import or the import fails, the UI resets cleanly instead of leaving an ambiguous in-progress state.

3 issues outstanding. Action required. See task

• Re-importing a task overwrites an existing Zoo tasks/<id> directory and can roll back newer Zoo-side history.
• Import failures from stale or inaccessible Roo storage paths are not surfaced to the user.
• Re-importing an already-imported Roo task now reports No Roo Code task history was found even though Roo history exists and Zoo only skipped copying because the destination already exists.
• platform-unit-test (windows-latest) is still pending after the bounded CI wait.
• platform-unit-test (ubuntu-latest) is still pending after the bounded CI wait.

How about creating a top level import export settings tab for discoverability? This way users can quickly find the page. We can also redirect users to this page with the import export link

Nice - This is so cool!

I did think about it, but this is a temporary issue until we complete the migration, and there are so many menu tabs already. I think this is a reasonable place to put it. I do think we should add a link in the readme and version announcement popup that links to the about section, showing the import of history etc.

Sounds good!

Couple of small tweaks

Add can you also add a regression test that runs two importRooTaskHistory() calls concurrently against the same Roo task and asserts the imported Zoo task directory contains the complete expected file set.
