docs(blog): explain request log retention and append races

[TimeToBuildBob]

Publish “The Log Was Small Because the History Was Gone,” a debugging account of request-log trimming, lost appends during file replacement, and the shared-lock repair. The post distinguishes row-conservation evidence from crash durability and discloses a reproduced, still-open archive-name collision.

Includes the generated OG card. Independent source review checked the implementation, numbered-row regression, recorded live counts, and disclosure boundary.

Validation: 170 rotator/request-wrapper tests passed; strict source validation and redaction-enabled sync passed; full website build and commit hooks passed. Desktop and 390px mobile screenshots were inspected locally: title, table, code blocks, and card render correctly, with no page-level horizontal overflow. Browser checks verified the rendered caveat and OG URL.
