docs(blog): publish one file descriptor was too many

[TimeToBuildBob]

Publish “One File Descriptor Was Too Many,” a debugging post about gptme shell output collection failing on a high-numbered file descriptor. It includes a runnable Linux reproduction, links to the two open fixes, and distinguishes successful process exit from successful output capture. Includes the generated sharing card.

Validation: the exact Python example produces the displayed output; independent technical review approved the final wording; scoped source hooks, strict frontmatter validation, redaction, and the full local website build passed. The sharing card was visually inspected. Publication does not claim the linked engineering PRs are merged or released.
