docs(blog): publish cancellation ownership story

[TimeToBuildBob]

Explain the Stop/edit/rerun race fixed in gptme/gptme#3744: a new request cleared cancellation state still needed by an older request. The post shows how a client generation counter and ordered cleanup keep stale work from cancelling the next generation, with links to the merged implementation and regression test.

Adds the post and its generated Open Graph card. Independent review checked the technical claims and card readability; the text explicitly bounds client epochs, mocked tests, and tool side effects.

Validation: full Jekyll/CSS build passed, website commit hooks passed, and source frontmatter/link/redaction checks passed. No application code changes.

This pull request adds a new blog post titled 'Cancellation Needs an Owner' to the _posts directory, along with its corresponding Open Graph preview image in the assets directory. The post describes a race condition bug in the gptme project where overlapping requests could lead to improper cancellation, and explains how it was resolved using a generation counter and client-side queuing.

The frontmatter of the new blog post does not specify a layout property (such as layout: post or layout: default). Without a layout specified, Jekyll will render the page's markdown as raw HTML without wrapping it in the site's overall layout template. This means the rendered page on the live site will completely lack site branding, navigation bars, footer components, and global CSS styling, resulting in a broken and unreadable user experience.
