ZDDC 8aebb0c346 fix(browse): propagate writable bit into tree nodes 
Root cause of "I'm root admin but the editor says read-only."

loader.js parses the listing JSON and stamps `writable` onto the raw
entry. tree.js:newNode() then copies every other field (name, url,
isDir, size, modTime, ext, handle, virtual …) into the tree node —
but dropped `writable`. So `node.writable` was always undefined and
`canSave(node)` short-circuited to false, mounting the YAML and
markdown editors read-only even for an elevated admin where the
server had correctly stamped writable=true.

Symptom: red banner / read-only mode regardless of admin status.
Server-side log line was correct (elevated=true active_admin=true
chain_admin_level=0); the bit just never reached the editor.

One-line fix: include `writable: !!raw.writable` alongside `virtual`
in the tree-node initialiser. Verified end-to-end against the live
bitnest fixture — every entry now carries the bit through.

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.
