c22bb19dab perf(server): gzip compression middleware on the entire mux
Add github.com/klauspost/compress/gzhttp wrapper around the request
handler. With MinSize(1024), responses ≥ 1 KB get gzip-encoded when
the client advertises Accept-Encoding: gzip; smaller bodies + 304
Not Modified pass through unchanged.

The wrapper auto-appends Vary: Accept-Encoding (compatible with the
existing Vary: Accept on directory.go's content-negotiated path).

Live-tested against zddc-server -root /tmp/empty:
  GET / w/ Accept-Encoding: gzip → 20.9 KB compressed (was 80.9 KB
                                   uncompressed). 74% reduction.
  Decompresses cleanly back to the original bytes.

Helps every code path that bypasses Caddy: devshell pods, local dev
binaries, tests, anywhere zddc-server is hit directly. Production
behind Caddy already had compression at the proxy layer; this just
makes the Go server self-sufficient.

Tests in cmd/zddc-server/main_test.go cover:
- large body + Accept-Encoding → compressed + Vary header
- small body → not compressed (under MinSize)
- no Accept-Encoding header → plain bytes

4ede42010a feat(zddc-server): CLI flags, --version, CWD-default ZDDC_ROOT
Adds command-line flags to zddc-server alongside the existing env vars.
Each setting can be set via --<flag-name> or ZDDC_<NAME>; the flag wins
on conflict, the env var wins over the hard-coded default.

  --root          / ZDDC_ROOT          (now defaults to CWD if both unset)
  --addr          / ZDDC_ADDR          (:8443)
  --tls-cert      / ZDDC_TLS_CERT      ("none" / empty / path)
  --tls-key       / ZDDC_TLS_KEY
  --log-level     / ZDDC_LOG_LEVEL     (info)
  --index-path    / ZDDC_INDEX_PATH    (.archive)
  --email-header  / ZDDC_EMAIL_HEADER  (X-Auth-Request-Email)
  --cors-origin   / ZDDC_CORS_ORIGIN   (https://zddc.varasys.io; "" disables)
  --insecure-direct / ZDDC_INSECURE_DIRECT (false)
  --help          (prints flag list to stderr, exits 0)
  --version       (prints binary + embedded tool versions, exits 0)

So an operator can `cd /srv/zddc && zddc-server` with zero config — the
served root defaults to the current directory, and TLS defaults to a
self-signed cert. config.Load now takes []string (test-friendly: nil
skips flag parsing entirely; tests pass an empty slice for env-only
loads).

Adds a `version` package-level var in main.go injected at link time via
`-ldflags="-X main.version=..."`. The build.sh runs git describe against
zddc-server-v* tags; for in-flight commits between releases it produces
e.g. zddc-server-v0.0.7-19-gadb6904-dirty.

Adds an embedded versions manifest:
  - Each tool's compute_build_label (in shared/build-lib.sh) writes a
    sidecar <tool>.label to $BUILD_LABELS_DIR if that env var is set.
  - Top-level build.sh sets BUILD_LABELS_DIR before running each tool's
    build, then assembles zddc/internal/apps/embedded/versions.txt as
    one `<app>=<build label>` line per app.
  - apps.EmbeddedVersions() loads the manifest at runtime.
  - main.go logs a compact summary on every startup; --version dumps
    the full per-app label.

Removes the old cfg.BuildVersion field — the X-ZDDC-Source: embedded
header now uses the package-level main.version directly.

8b6a2dc3e3 feat(zddc-server): apps fetch+cache subsystem with cascade overrides
Adds internal/apps/ package serving the five tool HTMLs at virtual paths
based on the surrounding folder name convention:

  archive      every directory (multi-project, project, archive, vendor)
  classifier   any Incoming/Working/Staging directory and subtree
  mdedit       any Working directory and subtree
  transmittal  any Staging directory and subtree
  landing      only at deployment root

The current-stable build of every tool is //go:embed'd into the binary
at compile time — that's the default with zero config. Operators
override per-directory via .zddc apps: entries; closer-to-leaf wins.

Spec syntax (in any apps: value):

  stable / beta / alpha / :stable          channel
  v0.0.4 / v0.0 / v0 / :v0.0.4              version
  https://my-mirror/releases                URL prefix only
  https://my-mirror/releases:beta           URL prefix + channel
  https://my-fork/archive.html              terminal full URL
  ./local.html / /abs/path.html             terminal local path

The special apps.default key provides a baseline URL prefix and channel
inherited by any app not overridden per-name. Per-axis cascade: a deeper
.zddc can override the URL, the channel, or both.

Cascade walks root→leaf; default applies first at each level, then the
per-app entry. Terminal sources (paths and full .html URLs) short-circuit
composition; deeper non-terminal entries override parent terminals.

URL sources fetch once on first request and cache forever in
<ZDDC_ROOT>/_app/<host>/<path> — different upstreams with the same
filename stay distinct. No background refresh, no SHA-256 verification:
operators delete the cache file to force a refetch. Concurrent misses
for the same source dedupe via a 30-line hand-rolled singleflight.

Per-request override: any user can append ?v=<spec> to a tool URL
(e.g. ?v=beta, ?v=v0.0.4, ?v=:alpha, ?v=https://mirror/releases:beta)
to ask for a different build for one request. Security: ?v= serves
ONLY versions already in the cache (cache miss returns 404; path
sources are rejected outright with 400). Users cannot trigger
arbitrary upstream fetches via crafted URLs.

Failed URL fetches (network down, 5xx) fall back to embedded with a
one-time WARN log. The X-ZDDC-Source response header reports what
served: fetch:URL / cache:URL / path:/abs / embedded:<app>@<build>.

Wire-in (cmd/zddc-server/main.go): dispatch routes <dir>/<app>.html
through apps.MatchAppHTML + AppAvailableAt + apps.Server.Serve when
no real file exists. Direct URL access to /_app/... is blocked at
the dispatch layer — cached files must go through the apps resolver
so they get correct Content-Type and ACL gating.

Schema (internal/zddc/file.go): ZddcFile gains Apps map[string]string
for cascade overrides. Validator (internal/zddc/validate.go) accepts
the special "default" key alongside the five canonical app names and
all spec forms.

Removes ZDDC_APPS_* env vars (no admin UI, no refresh interval, no
upstream allow-list — the simpler model has fewer knobs).

40+ unit tests across the new package: parser shapes, cascade
resolution with default+per-app interactions, terminal short-circuit
semantics, ?v= cache-only enforcement, embedded fallback, atomic
cache writes, singleflight dedup. Plus end-to-end dispatch tests in
cmd/zddc-server/main_test.go.

cb46c2ef8c feat(zddc-server): user profile page replaces /.admin/
Replaces the super-admin-only /.admin/ surface with a public-by-default
/.profile/ page that layers admin tools server-side based on the
caller's effective access:

- Universal (everyone, anonymous included): identity card, effective
  access summary, theme picker, localStorage utilities (export / import
  / clear, landing-presets viewer).
- Subtree admins additionally see: editable .zddc files list (linking
  to the existing form-based editor) and a "Create new project folder"
  form.
- Super-admins additionally see: server config, log viewer, whoami
  headers (the old /.admin/ JSON endpoints, repointed under /.profile/).

Project creation is gated on CanEditZddc(newDir) — the same strict-
ancestor rule that already governs .zddc writes — so no new authority
concept is introduced. ValidateProjectName mirrors the existing
reserved-prefix policy (no leading '.' or '_', no path separators).

/.admin/* is hard-cut: no redirect shim. Old URLs fall through to the
existing dot-prefix guard and 404. Custom CSS file rename: prefer
<root>/.profile.css, fall back to legacy <root>/.admin.css.

Per-resource 404 leakage gates preserved on whoami / config / logs /
zddc / projects so non-admin callers cannot detect the existence of
admin-only sub-resources.

Tree-wide gofmt -w applied as a side-effect.

9ef90800b1 feat(zddc-server): admin debug page + X-Auth-Request-Email default + hidden-segment guard
Three improvements bundled because they all ship as zddc-server v0.0.2:

* /.admin/ debug dashboard with /whoami, /config, /logs sub-routes.
  Authorization via a top-level `admins:` glob list in <ZDDC_ROOT>/.zddc
  (root-only — subdir entries deliberately ignored to prevent privilege
  escalation via subtree write access). Non-admin requests get 404 so the
  page is invisible. Recent logs surface via a 500-entry slog ring buffer
  teed off the existing TextHandler. Lets operators debug without
  kubectl exec.

* Default ZDDC_EMAIL_HEADER changes from `X-Email` to
  `X-Auth-Request-Email` — the oauth2-proxy / nginx auth-request
  convention that the TND helm chart already sets explicitly.
  Operators who set the env var explicitly are unaffected; deployments
  relying on the previous default need to set ZDDC_EMAIL_HEADER=X-Email
  or update their proxy.

* dispatch() rejects any URL whose segments contain a dot prefix other
  than the recognized virtual prefixes (.admin, cfg.IndexPath /
  .archive). Matches the existing listing-pipeline filter so hidden
  subtrees on the served PVC (e.g. /srv/.devshell — used by the
  in-cluster dev-shell for persistent home-dir state) become
  unreachable via direct HTTP fetch, not just hidden in listings.

Refreshes the X-Email reference in website/index.html accordingly.
