Subject: [PATCH] fix: OTLP nanosecond timestamp overflow from IEEE 754
 precision loss

Convert epoch milliseconds to BigInt before multiplying by 1,000,000
to avoid IEEE 754 precision loss. The result of epoch_ms * 1e6 (~1.7e18)
exceeds Number.MAX_SAFE_INTEGER (~9e15), causing ~256ns errors.

Fixes triggerdotdev/trigger.dev#3292
