feat(zddc): Phase 4c — stage strip driven by cascade-declared children

Browse source 
The shared/nav.js stage strip previously hardcoded four stages
(archive/working/staging/reviewing) with their labels and target
URLs baked into the file. Operators couldn't add a fifth stage or
rename "Working" to "In-Progress" without forking shared code.

Now cascade-driven end-to-end:

  Server-side:
    listing.FileInfo gains a Declared bool field. fs.ListDirectory
    stamps Declared=true on every entry whose name matches the
    cascade's ChildrenDeclaredAt(parent) — both real on-disk dirs
    and virtual canonical injections. Bugfix in the same patch:
    virtualCanonicalFolders was passing the relative dirPath to
    ChildrenDeclaredAt (which expects absolute); now passes absDir.

  Client-side:
    shared/nav.js fetches the project root's JSON listing on
    DOMContentLoaded, filters to declared+is_dir entries, sorts by
    canonical workflow order (archive → working → staging →
    reviewing, then any extras alphabetically), and renders the
    strip. Labels read e.display_name → falls back to titleCase(name).

    Hardcoded FALLBACK_STAGES kicks in only on fetch failure
    (offline / file:// / non-zddc-server backend). Rendered
    immediately so the strip appears without flicker, then the
    cascade-fetched list replaces it once available.

  Effect:
    Project-3 (which has display: { archive: "Records",
    working: "In-Progress", ... } in its .zddc) now shows
    "Records · In-Progress · Outbox · Pending Responses" in every
    tool's strip. Project-1 still shows "Archive · Working ·
    Staging · Reviewing". No code change to render either; the
    cascade decides.

Tests:
  - tests/nav.spec.js relies on the mock server returning HTML at
    every URL, so the fetch fails over to fallback stages — the
    test renders the same Archive/Working/Staging/Reviewing labels
    it always did, with no test changes needed.
  - All 248 Playwright + all Go tests green.

Remaining client-side hardcode: archive/js/source.js +
archive/js/app.js's mode detection. Phase 4d.
