chore(bots): bump engine pin to 5368de77 (can_use_tool PermissionResult fix)

Moves the engine pin (bot-prelude's single engine-ref default) from 3569dae3 to
5368de77, which includes databricks/databricks-bot-engine#122 — the fix for the
can_use_tool permission callback returning a dict instead of a PermissionResult
object. Without it, every edit_file/bash call the engineer bot makes fails with
`TypeError: Tool permission callback must return PermissionResult ... got dict`,
so the bot can read but not edit or run tests (observed on #791: two runs hung to
the 45-min job timeout). The fix is runtime-verified against the pinned SDK
(0.2.102).
