Feat: Entity auto registration in topology

[harshsoni2024]

Describe your changes:

Auto-registration in the Topology Framework

Problem:

• Every connector must manually call self.register_record_(request) after yield Either(right=request). If a connector forgets self.register_record_, mark__as_deleted sees an empty source state and soft-deletes every entity for that service.

Improvement:

• Add a source_state field to NodeStage that names the attribute on the source where FQNs should be collected. The topology runner auto-registers entity FQNs into this set after a successful yield — no connector code needed.

Type of change:

• Bug fix
• Improvement
• New feature
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Documentation

Checklist:

• I have read the CONTRIBUTING document.
• My PR title is Fixes <issue-number>: <short explanation>
• I have commented on my code, particularly in hard-to-understand areas.
• For JSON Schema changes: I updated the migration scripts or explained why it is not needed.
