improvement(comparison): cite Sim's own docs alongside code for 4 facts

Added docs.sim.ai citations (Roles and Permissions, BYOK, Debugging
retrieval, Function block) as primary sources for rbac, byok,
kbChunkVisibility, and customCodeSteps, which previously cited only
GitHub source code with no user-facing documentation reference.
Verified all 4 doc URLs resolve (200).
