release: backfill HTML-tool stable releases on Codeberg + drop local mirrors

Completes the deferred cleanup from 2dc9ad2 ("refactor: distribute via
Codeberg release assets, drop the upstream image"), now that
$CODEBERG_TOKEN is provisioned.

Backfilled to Codeberg release assets:
- archive, transmittal, classifier, mdedit, landing — v0.0.1 and v0.0.2
  stable releases (10 releases, one HTML asset each)
- zddc-server v0.0.8-alpha.2 — four cross-compiled binaries (the same
  artifacts that previously lived in website/releases/, renamed to the
  canonical zddc-server-<os>-<arch>[.exe] without the -alpha suffix)

Older zddc-server stable tags (v0.0.1 through v0.0.7) are not
backfilled — they were image-only releases under the old flow and have
no binary artifacts to upload. Operators wanting those builds can
checkout the tag and run `sh zddc/release.sh stable <ver>` to publish
binaries; nothing in the new flow depends on them existing on Codeberg.

Removes from the working tree (now redundant — Codeberg is canonical):
- website/releases/<tool>_v0.0.{1,2}.html  (10 files)
- website/releases/<tool>_{alpha,beta}.html  (10 files; mutable channel
  mirrors written by the old build flow)
- website/releases/<tool>_stable.html  (5 symlinks)
- website/releases/zddc-server-*-alpha[.exe]  (4 binaries)

Also: regenerates website/releases/{index.html,manifest.json} from the
post-backfill Codeberg release list. The manifest currently has stable
entries for the five HTML tools and an alpha entry for zddc-server;
HTML alpha/beta channels and zddc-server stable will populate as
operators cut those releases through the new flow.

One repo-config side effect: enabled the "Releases" repo unit on
codeberg.org/VARASYS/ZDDC (was off; the API returned 404 on every
release endpoint until enabled).
