ZDDC 9972e6773a feat(browse): markdown version-history viewer with diff + restore
Adds a "History…" context-menu item on markdown files in a history:true
subtree (server mode only — the audit is server-stamped). It opens a modal
that lists every saved version newest-first (timestamp + author + size,
current flagged), lets you View any version, Diff any two, and Restore one
(a forward PUT — non-destructive).

- shared/diff.js: dependency-free line/word LCS diff (window.zddc.diff),
  prefix/suffix trimming + a cell cap so large files don't stall the UI.
- browse/js/history.js: the modal (list / view / diff / restore), talking to
  GET <url>?history=1 and ?history=<sha>.
- loader.js carries the per-file history flag; events.js adds the menu item.
- Wired diff.js + history.js + history.css into browse/build.sh; diff.js into
  the zddc-test.html shim. tests/diff.spec.js covers the diff algorithm.

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.
