fix: address review comments in runtime and stop handler GIT-869c63k1e

Use CLOCK_SKEW_ALLOWANCE_MS constant and remove uninitialized handlerResult path.

AI-Agent: Codex/0.92.0
AI-Model: gpt-5.3-codex
AI-Decision: Clock skew allowance for runtime data validation is set to 1 minute (60,000ms) to handle minor timestamp discrepancies between systems.
