chore(blog): repair front matter, links and bundle names (#642)

## Summary

Brings every blog post in line with the rules the publishing checks in
#640 enforce: **83 posts, zero errors**, verified against a full
production build.

This is the content-side companion to #640. With it merged, the
validation job there can stay strict from day one.

## Front matter

Nine posts had no `author` and no `description`. Both feed the meta
description and the JSON-LD `BlogPosting`, so an empty description
leaves search results and structured data blank.

The author of each was taken from the `**Author**:` line the post
already carried in its own body — **not** from git history. That
distinction matters here: all nine were committed by the same person,
while the posts themselves were written by two different authors. Going
by the committer would have credited five articles to the wrong person.

Descriptions are written from the content of each post.

## Links

36 dead targets repaired:

- The bulk pointed at `/docs/v1/`, a version directory that has never
existed. Retargeted to `v1.6`.
- Blog cross-links in the DIY series carried a day segment
(`/blog/2024/04/05/...`), which the permalink pattern does not produce.
- Two pages had moved: `virtualization/gpu-passthrough` is now
`virtualization/gpu`, and `applications/virtual-machine` is now
`virtualization/vm-instance`.
- A link to the Kubefarm article was written as internal, although it
lives on kubernetes.io — part 3 of the same series already links to it
correctly.
- `/community/` does not exist; that link now points at the community
meeting calendar directly.

Every replacement was verified to exist, either in the build or with a
request against the live site.

## Directory names

Five bundles disagreed with their own front matter about slug or date,
and two carried no date prefix at all.

The directories were renamed rather than the front matter edited, and
that direction is deliberate: permalinks derive from `slug` and `date`,
so renaming the directory leaves **every published URL untouched**.
Verified for all five after the change.

## Verification

`python3 hack/mcp/server.py --check` from #640, against a full build: 83
posts, no errors.
