ZDDC e2179d167b feat(browse): capability/role/tier-driven, context-correct menu system 
Reworks the browse menu/tree interaction into a declarative, contextually
honest model and moves view settings onto a toolbar — the menu is the UI to
the system, so it should be familiar, inviting, and only ever offer what
applies.

New declarative menu model (browse/js/menu-model.js):
- Every action is one descriptor with a TYPE predicate (appliesTo) and a
  CAPABILITY predicate (enabled)+tooltip. Row/pane menus are projections over
  it; separators are derived from group changes. Designed data-shaped so a
  future server-sourced manifest (zddc.zip) can supply/extend it.
- Hybrid visibility: type-inapplicable actions are OMITTED (New folder on a
  file, Expand on a file); permission/role/tier-gated actions are SHOWN
  DISABLED with a reason — so a lower tier sees what a higher role unlocks.
- Roles are NOT hardcoded: ordinary actions gate on the verbs the server
  returns (node.verbs / path_verbs), so any operator-defined role works. Only
  the two intrinsically-special tiers are recognised by name — site admin
  (is_super_admin) and project/subtree admin (path_is_admin), surfaced as the
  "Edit access rules…" item; both come from the existing /.profile/access.
- The headline fix: New folder / New markdown file no longer appear on file
  rows (they target a folder or the current dir).

events.js: deletes the ~350-line inline buildTreeRowMenu/buildPaneMenu/
SORT_BY_ITEMS; opens menus via menuModel projections through one openRowMenuFor
/openPaneMenu path shared by right-click, the hover kebab, and the keyboard
menu key (ContextMenu / Shift+F10). Injects action impls via menuModel.configure
to avoid a circular dep. Prefetches the scope /.profile/access (memoised) on
load/rescope/refresh/popstate so menus never fetch at open time.

Discoverability + a11y: a per-row ⋯ kebab (tree.js + new icon-ellipsis sprite,
revealed on hover/selection/focus) opens the same menu; keyboard menu key
supported.

Toolbar: Sort + Show-hidden moved OUT of per-row right-click menus into the
tree-pane toolbar, plus New folder / New file buttons (act on the current dir,
greyed with a reason when create access is lacking). Help copy updated.

Icons: dropped the 3 stray emoji from menu items (consistent, VS Code/Finder
style); only new sprite is the kebab's icon-ellipsis.

Tests: +5 browse specs (file row omits New-folder; folder row shows it; a
read-only server node greys Rename with a "write access" tooltip via a pure
menuModel unit; toolbar Sort/Show-hidden drive state + New buttons present;
kebab and Shift+F10 both open the menu). All 23 browse+conflict+diff green.

browse — directory listing tool

Generic file browser for any directory. Designed to work with ZDDC archives but useful for any folder. Single-file HTML, no install.

How it's used

Two modes, auto-detected at page load:

  1. Online (zddc-server backed). When this HTML is served by zddc-server at a folder URL — which it is by default for any directory under ZDDC_ROOT that doesn't have an index.html — the JS queries the same URL with Accept: application/json to load the directory's listing and renders it as a sortable, filterable table.

  2. Local (FileSystemAccessAPI). Click "Select Directory" in the header to pick any folder on your computer. Works in Chromium-based browsers (Chrome, Edge, Brave, etc.). No server required; the directory is read directly from disk.

What it does

  • Lists files and folders with name, size, type (extension), and modified date.
  • Click a folder to expand inline. Children load lazily on first expand.
  • Click a column header to sort by that column. Click again to reverse.
  • Type in the filter to narrow to entries whose name contains the substring.
  • Click any file to open it in a new tab — for server-backed pages, this routes through zddc-server's normal handler (so an .archive redirect, an apps cascade override, etc. all work as expected).

Design notes

  • No ZDDC-specific filtering. This tool is intentionally domain-agnostic. The companion archive tool layers ZDDC parsing (project / status / revision filters, tracking-number resolution) on top of the same listing API. Use archive when you want ZDDC semantics; use browse when you just want to see what's in a folder.
  • Default at directory URLs. zddc-server's directory.go serves the embedded browse.html bytes for any directory request with Accept: text/html and no index.html present. This means a user navigating to any folder under ZDDC_ROOT gets a usable browser without anyone having to drop a file into the archive.
  • Apps cascade override. Like every other ZDDC tool, the served browse.html can be overridden per-folder via a .zddc apps: entry. The default is the embedded copy from the binary; operators can pin a specific version or URL if they want.
