ZDDC 7570fb7494 refactor: separate website repo + deploy-host model
Migrates from in-repo orphan `website` branch + LFS to a two-repo +
deploy-host model so source editing is fully decoupled from live state.

  - Source code stays here (codeberg.org/VARASYS/ZDDC).
  - Hand-edited website content moves to a separate Codeberg repo
    (codeberg.org/VARASYS/ZDDC-website, cloned at ~/src/zddc-website/).
  - Live site is /srv/zddc/ on the deploy host (Caddy bind-mount),
    populated by ./deploy from this repo's dist/release-output/ plus
    ~/src/zddc-website/.
  - Releases are no longer in any git history — reproducible from
    <tool>-vX.Y.Z tags via `./build release X.Y.Z`. No LFS, no
    Codeberg release assets.

Build/deploy split:
  - ./build (no arg) is source-only; nothing in dist/release-output/
    or /srv/zddc/ is touched.
  - ./build alpha|beta|release seeds dist/release-output/ from
    /srv/zddc/releases/ (preserving symlinks), then mutates the
    channel(s) being cut on top. The bundle is always a complete
    intended-live snapshot, so the verifier sees a complete world
    and ./deploy --releases (rsync --delete-after) replaces live
    state cleanly.
  - New ./deploy wraps the rsync flow with --content / --releases
    subcommands.

Docs updated to reflect the new model: CLAUDE.md, AGENTS.md,
ARCHITECTURE.md, zddc/README.md, README.md, .gitignore, shared/
build-lib.sh comments, deprecated zddc/release.sh message.

# ZDDC shared build helpers — sourced by each tool's build.sh
#
# Usage in a tool build.sh:
# root_dir=$(cd "$(dirname "$0")" && pwd)
# . "$root_dir/../shared/build-lib.sh"
#
# Provides:
# ensure_exists <path> — abort with error if file missing
# concat_files <file ...> — cat each relative path under $root_dir
# build_timestamp — ISO UTC timestamp string, set at source time;
# used as build_label for dev builds
# escape_js_close_tags <in> <out>
# — copy <in> to <out> with all '</' rewritten as
# '<\/' so the HTML parser cannot misread the
# inlined JS as containing a closing </script>.
# The JS engine treats \/ as a regular slash,
# so runtime behaviour is unchanged.
# compute_build_label <tool> [--release [<channel-or-version>]]
# — sets globals: build_label, build_version,
# is_release, is_red, channel.
# See "Channels and release args" below.
# promote_release <tool> — for stable / alpha / beta, copy the dist
# HTML into the release-output bundle
# (default $root_dir/../dist/release-output;
# override $ZDDC_DEPLOY_RELEASES_DIR). Stable
# cuts write the immutable per-version file +
# refresh five symlinks (_v<X.Y>, _v<X>,
# _stable, _beta, _alpha) and tag
# <tool>-v<X.Y.Z>. Alpha/beta cuts
# overwrite the channel mirror in place
# and cascade alpha → beta. No git tags
# for alpha/beta cuts. The bundle is a
# complete intended-live snapshot — the
# top-level ./build seeds it from
# /srv/zddc/releases/ before per-tool
# promote runs, then ./deploy --releases
# rsyncs it back. See ARCHITECTURE.md
# "Channels" for the full table.
#
# Channels and release args:
# <none> dev build, tool/dist/ only, label
# "v<next-stable>-alpha · <ts> · <sha>[-dirty]" (red).
# No release-output side-effect. To produce a deployable
# bundle, re-run with `--release alpha`.
# --release stable, auto-bump patch from latest tag (or 0.0.1).
# Writes per-version file + symlinks; tags vX.Y.Z.
# --release X.Y.Z stable, explicit version.
# --release alpha alpha channel cut at HEAD;
# label "v<next-stable>-alpha · <date> · <sha>" (red).
# Overwrites <tool>_alpha.html. No tag.
# --release beta beta channel; label "v<next-stable>-beta · <date> · <sha>".
# Overwrites <tool>_beta.html. Cascades <tool>_alpha.html
# → <tool>_beta.html (symlink). No tag.
