Store tool call ID and infer interception relationships

[dannykopping]

Depends on coder/aibridge#165

Implement the coder/coder aspect of persisting the tool call IDs, and use this to infer relationships between two interceptions. See https://www.notion.so/coderhq/DRAFT-AI-Bridge-Prompt-Provenance-2ccd579be59280f28021d3baf7472fbe?source=copy_link#2ccd579be59280d3923ecfb8e5128dae.

All tool calls triggered by an initial prompt should be linked back to the original (parent) interception.

Acceptance criteria:

• Migrations to add new columns
• Proto updated to accept tool call ID in RecordInterceptionEndedRequest
• aibridgedserver handling of RecordInterceptionEnded to store tool call ID
• Database query to find other interception with matching tool call ID
• Database query to update child interception with parent interception ID
• Tests added

See POC (enterprise/aibridgedserver/aibridgedserver.go -> findInterceptionLineage)
