ZDDC 85e6eb152c fix(browse): save-button gate reads canSave at click time 
The markdown editor's save handlers (markDirty, save(), convertBtns
intercept) referenced a bare identifier `writable` that never existed
in their scope — the captured variable was named `writableMode`. JS
silently evaluates `!undefined` to true, so saveBtn.disabled stayed
true forever and Ctrl-S was a no-op. The download-as-* intercept
treated every dirty file as read-only and offered the "save a copy
elsewhere" toast.

YAML editor had the matching-name pattern (`writable` defined and
referenced) so the symptom was hidden, but the same stale-closure
shape: capture once at mount, never re-read when the underlying tree
node's writable bit changed.

Fix both: gating logic reads canSave(node) fresh at every click, not
from a closure. Mount-time captures stay for initial UI shape
(read-only banner, CodeMirror readOnly:'nocursor') where the decision
is correct at the moment it's applied.

Codify the pattern in AGENTS.md § "JS module pattern":
no bundler + no reactivity layer ⇒ closures don't refresh ⇒ read
fresh in handlers, never cache.

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.
