What changed

This adds five people whose work shipped in 0.1.4 to CONTRIBUTORS.md:

• Saba Siddique wrote the OTLP trace exporter (PR Export Guardian traces as OTLP to a file and over HTTP #244) and the skill lifecycle hook mappings (PR Add the skill lifecycle hooks to the Trace mappings #63), and reported the OCSF rename that became PR Pin the OCSF mapping to 1.9.0 and use OCSF's class names #258.
• Prem Methuku opened issue [Bug] §6.4's mandatory fail-open audit event has no conformant shape, so the decision-failure rate is unmeasurable #37, which led to the acs.decision.failure event. His measurements are why payload_bytes is in it.
• Sankalp Gilda, @narko4u and @ossumpossum pushed on issue [Bug] §6.4's mandatory fail-open audit event has no conformant shape, so the decision-failure rate is unmeasurable #37 to make that event's count verifiable, as Bar's decision there says.

The list stays alphabetical. Names come from each GitHub profile, and handles stand in where a profile has no personal name.

Admin-merged on the project lead's call. It only adds five contributors whose work shipped in 0.1.4, so they're credited alongside the release.
