This commit addresses two related issues: - Issue #95: Unhelpful error messages when user lacks channel edit permissions - Issue #434: Files downloaded/uploaded before checking permissions Changes: - Added early permission check in commands.py after channel construction - Calls add_channel() before DOWNLOAD_FILES stage to fail fast if unauthorized - Caches root_id and channel_id to avoid duplicate API calls - Prevents wasted bandwidth and processing time Benefits: - Users get immediate feedback on authorization issues - No wasted resources downloading/uploading files when unauthorized - No Studio API changes required - uses existing endpoints - Backward compatible with existing chef scripts

Thanks, Richard. Code changes make sense, and I have smoke-tested this with tokens with and without permissions, and can confirm that this now fails early for non-authorized users with a readable auth error message.

Just out of curiosity. Would there be any state when we reach this point, but the add_channel hasn't been called yet?

I would really hope not - but maybe if someone subclassed the tree manager somewhere and overrode the place we do the initial check?

Probably the best way to test this would be to edit the tests/test_chef_integration.py to use a static channel domain and channel source id.
Then run with one Studio user token, then run it again with another (non-admin) Studio user token.
When I did this, it gave me a properly semantic error message before downloading any files telling me I didn't have permission to edit the channel
