🔒 [security] replace Date.now() with randomUUID() for STIX bundle IDs

[miccy]

🎯 What: The vulnerability fixed

Replaced insecure Date.now() with crypto.randomUUID() for generating STIX bundle IDs in packages/engine/src/extractor/ioc.ts.

⚠️ Risk: The potential impact if left unfixed

Using Date.now() for identifier generation is insecure as it is predictable and has a high risk of collisions in high-throughput or distributed environments. This could lead to data integrity issues or potential exploitation where unique identifiers are expected.

🛡️ Solution: How the fix addresses the vulnerability

The fix utilizes the node:crypto module's randomUUID() function to generate cryptographically secure UUIDv4 identifiers. A new test case has been added to packages/engine/src/extractor/ioc.test.ts to verify that the generated IDs follow the bundle--<UUIDv4> format.
