DRAFT: Add enterprise + multi-org collection support

[d3vzer0]

Add GitHub Enterprise ingestion with multi-organization support. Additionally, adds new nodes/edges for Github Workflows.

Changes:

• Add enterprise resource collector for enterprise orgs, members, teams etc.
• Add org_login/environment id for lookups to support multi-org collection via enterprise credentials
• Adds a parser for Github workflows with matching against existing repo/org/environment variables and secrets.
• Additionally fixes an issue when the GraphQL helper returns no pagination metadata while this is required by the Pydantic model
• Simplifies doc-generation descriptions for node properties via docstrings instead of dataclass field metadata

• self.org_node_id is str | None, but this code unconditionally calls .upper() when building org-variable property matchers. If lookup returns None, this will raise at runtime. Guard on self.org_node_id before calling .upper() (and skip emitting the edge if it’s missing).
