#780 [Bug]: skills.sh still renders stale SKILL.md after source update + fresh reinstall

Description

The skills.sh page for my public skill is still rendering an older ingested copy of SKILL.md even though the GitHub source has been updated and a fresh install was performed afterward.

Affected skill:

Live page: https://skills.sh/blastgits/blastgit-auto-pr/blastgit-auto-pr
Repo: https://github.com/Blastgits/blastgit-auto-pr
Current source: https://raw.githubusercontent.com/Blastgits/blastgit-auto-pr/main/SKILL.md
Commit that removed the stale Codex wording: https://github.com/Blastgits/blastgit-auto-pr/commit/04ec4679d26a38b2d975976e292305da64c38666

What is stale on skills.sh

The live page still says:

It helps Codex discover promising repos...

But the current repo source now says:

It helps an agent discover promising repos...

There are no remaining Codex references in the published repository.

Reproduction / evidence

View the live skill page:
- https://skills.sh/blastgits/blastgit-auto-pr/blastgit-auto-pr
- It still renders the older Codex wording.
View the current raw source:
- https://raw.githubusercontent.com/Blastgits/blastgit-auto-pr/main/SKILL.md
- It shows the updated agent-neutral wording.
Perform a fresh install from the updated public repo:
- npx -y skills add https://github.com/Blastgits/blastgit-auto-pr --skill blastgit-auto-pr --yes --global
- Install succeeds, but the page still renders the old content afterward.

I also checked the live response headers after the reinstall and the skill page was still being served as a stale prerendered page:

x-vercel-cache: STALE
x-nextjs-stale-time: 300

Expected behavior

After the repo's SKILL.md changes and a new install occurs, the skills.sh skill page should refresh to the current GitHub content.

Actual behavior

The skill page continues to show the older markdown snapshot.

Notes

This may be related to the same stale-source family as #703, but this repro does not involve a repo rename. It is the same repo path with updated SKILL.md content.
