Address issue #222

[dotsdl]

This commit introduces a new scopes_exclude configuration parameter for compute services, addressing issue #222.

Changes:

• Added scopes_exclude field to ComputeServiceSettings with validation
• Updated ComputeService to initialize and pass scopes_exclude to client
• Updated ComputeClient.claim_tasks() to accept and transmit scopes_exclude
• Updated compute API /claim endpoint to filter taskhubs based on excluded scopes
• Filtering uses Scope.is_superset() to exclude taskhubs matching excluded scopes

The scopes_exclude option is applied after scopes as a filter, allowing users to specify broad scopes while excluding specific subset scopes from task claiming.

Fixes #222
