docs(specs): 018 record the v0.3.0 release and close out tasks

[ValgulNecron]

Summary

• audit/rounds.md § v0.3.0: the tag, release run 37411911079 (all jobs green), image and chart signing, the non-prerelease GitHub release, the notes taken from ## [0.3.0], and the 0.3 image tag (T073).
• audit/evidence/final-validation.txt: output of the quickstart final-validation greps (T075). Checks 1 and 2 are not met (RC-01, RC-03); both were accepted as known risk at the go decision.
• tasks.md: T054 and T066–T073, T075 are marked done. The remaining live-round, fix-loop, upgrade, node and security tasks are withdrawn, citing the T070 go decision. T034 and T074 stay open: kubelab stays on v0.3.0, and the final cleanup check runs on the maintainer's devbox.
• release-criteria.md RC-08 stays pending. The ci push run on the tagged commit was cancelled by later master merges, so it will be re-run and RC-08 set afterwards.

The tag-triggered screenshot refresh workflow failed, but it has failed on every run since 2026-09-06. It is noted in rounds.md and is not a release criterion.
