feat(content): rewrite hardcoded blob URLs in markdown frontmatter to new hostname

#32

What to build

Rewrite every hardcoded blob URL in markdown frontmatter / body to point at the new website-blob hostname. Only the host changes; pathnames are preserved.

Steps:

1. Update BLOB_BASE_URL constant in posts/scripts/update-asset-urls.js from the old hostname (jr0deqtyc8c5pvr8.public.blob.vercel-storage.com) to the new store hostname captured in feat(blob): create website-blob store under Ocobo team account #35.
2. Run pnpm update-urls over every .md in blog/, stories/, team/, jobs/, tools/, legal/.
3. Verify with git diff that only the hostname changed and no path was mangled. Spot-check a few rewritten files.
4. Commit atomically: chore(content): rewrite frontmatter blob URLs to new website-blob hostname.

The rewrite must be idempotent — re-running the script after the commit produces an empty diff.

Acceptance criteria

• BLOB_BASE_URL updated in scripts/update-asset-urls.js to new store hostname
• All hardcoded blob URLs in .md files rewritten to new hostname
• Pathnames unchanged (only the hostname differs in the diff)
• Script is idempotent (second run produces no diff)
• Commit message follows conventional format
• Spot-check at least 1 file per content type (blog, story, team, job, tool) confirms correct rewrite

Blocked by

• feat(blob): push cleaned posts/assets/ to new website-blob store #36
