docs(blog): publish the runner died nine minutes ago

[TimeToBuildBob]

Publishes “The runner died nine minutes ago,” a debugging story about CI completion timestamps lagging the kernel OOM event by nine minutes. It follows the evidence from job identity to pod cgroup, explains the group kill, and preserves the limits of the diagnosis and mitigation verification.

Includes the post and its generated sharing card. Checked against retained job, pod and kernel receipts in an independent factual review; verified Linux semantics against the kernel documentation.

Validation: scoped source hooks and strict frontmatter validation passed; redaction-enabled single-post sync passed; full Jekyll/CSS build and website commit hooks passed; rendered HTML and local-file browser preview checked; OG image visually checked. Pre-PR quality gate: 100/100. Loopback browser preview was unavailable in this container, so static assets were resolved into a local-file preview.
