docs(contributing): the examples repo is archived; make its page say so

[adnaan]

/contributing/examples described how to contribute to livetemplate/examples. GitHub has that repository archived and read-only, so the workflow it documented cannot be followed.

It told the reader to create a directory there, write a go.mod pinning livetemplate v0.1.0 (core is at v0.25.0), and add a README in exactly the register #137 spent a PR removing from the ten pages that had copied it.

Two things that were not obvious

The page was never actually mirrored. It carries source_repo front matter pointing at the archived repo — but /contributing/examples has no entry in source-of-truth.yaml, and cmd/sync only walks entries from that file:

cfg, err := loadSourceOfTruth(cfgPath)
matched := filterByRepo(cfg.Pages, opts.SourceRepo)

Nothing scans front matter. So the page was already docs-native and merely mislabelled, and correcting the front matter changes no sync behaviour.

Both maps said otherwise. source-of-truth.md had it as Mirror? yes, and CLAUDE.md listed all of content/contributing/* as mirrored. Both now carve out this page and say why — otherwise the next person reads "mirrored" and skips it as unfixable, which is roughly what happened.

What the page says now

That the repo is archived, that examples live in this repo under examples/<slug>/, and where the current steps are. It repeats the two rules that have already cost real work here: include code rather than retyping it (the chat recipe documented a Change(ctx *ActionContext) API that never existed for as long as it was hand-written), and read VOICE.md before writing the prose.

619 words → 41 lines.

Verification

voice-check.sh failed on this page twice before passing, and both were mine:

1. it quotes a banned phrase as an example of what not to write, and the check can't tell mention from use — reworded rather than exempted
2. three passives in my own new prose — fixed rather than raising the ceiling from 34

Then: tinkerdown validate 98/98, go test ./e2e/... green uncached, and the page read back in a real browser with all six links resolving.

Adjacent, not fixed here

The archived repo is still advertised as live from mirrored pages I can't edit from this repo — contributing/livetemplate.md has git clone https://github.com/livetemplate/examples.git twice, plus references in client/index.md, reference/client-attributes.md and guides/standard-html-reactivity.md. Those need upstream PRs.
