Adds the 3.6 MB take-3 walkthrough mp4 that README already references
via a poster image, and replaces the "coming in a follow-up commit"
placeholder line with a real link (poster now click-through to the
video, caption points at the same file).

No source or config changes; the shell tree from a3ca492a is byte-
identical to what it was, this commit just fills in the recording
slot the previous docs commit deferred.
Expanded README landing page for first-time cloners: Pages & Features
guide walks through each of the 14 UI surfaces (chat, trace timeline,
subagent panel, context surface, rubrics, plugins, compaction, budget,
etc.) with 2-4 sentences on what each page shows and why it exists.
Feature highlights section lists 10 concrete affordances a plugin
author or researcher would want to know are there.
Quick Start rewritten for the cold-clone path:
- two-step pnpm install (repo root for tsx, then examples/desktop for
Electron) — resolves the P0-5 install failure a fresh clone hits
- HARNESS_DEV layouts documented: in-repo (default when cloning
deepseek-harness), sibling deepseek-harness-dev/ (original dev
workflow), DSH_DEV_ROOT env (custom layouts)
- .env locations described relative to the runtime root rather than
hardcoded paths
- Profiles table reordered with stdio-echo first (keyless, works on
master); daemon-echo and daemon-vibe-echo marked 'Not yet available
on master' with a note pointing at the integration worktree
Facts-only tone; the only referenced assets are 01-overview.png,
03-chat.png, and video-poster.png in docs/readme-shots/ — all present
in the release tree.
Minimal Electron shell over the DSH JSON-RPC runtime — a first-look at
what a ChatGPT.app-style host on top of the DeepSeek Harness looks
like, with the harness's normally-invisible internals (trace timeline,
context surface, subagent tree, compaction, plugin registry, rubrics)
brought forward as first-class UI surfaces so plugin authors and
researchers can see what the agent is actually doing.
Runs against three keyless-to-live profiles (stdio-echo works on
master out of the box; daemon-echo / daemon-vibe-echo activate once
the daemon-demo lands; stdio-deepseek and daemon-vibe hit the real
DeepSeek API when you supply a key). HARNESS_DEV auto-resolves to the
in-repo runtime when this shell ships under examples/desktop/, so a
fresh clone launches without config; env DSH_DEV_ROOT overrides for
custom layouts, and a sibling deepseek-harness-dev/ checkout is the
original dev workflow.
Cold-clone gate (P0 fixes for first-time-clone usability):
- HARNESS_DEV: 3-candidate resolver (env → walk-up in-repo marker →
sibling), unit-tested via mock fs so ordering is locked without
needing either real layout on disk.
- config yml leaves rewritten at assemble time so the sibling-clone
paths (../../deepseek-harness-dev/examples/echo-agent/…) become
the in-repo paths (../../echo-agent/…) in the released tree —
source yml stays usable for local dev, released tree ships a
working shape.
- pnpm-workspace.yaml allowBuilds.electron = true (was placeholder).
- missing-key card in stdio-deepseek offers a one-click switch to
stdio-echo (the keyless profile that works on master) rather than
daemon-echo (blocked on the not-yet-shipped daemon-demo).
- assemble-oss-release.sh rewrites the source-side breadcrumb name
'dsh-desktop-demo' → 'dsh-desktop' for the released package.json.
FOUC guard on the onboarding gate (41fc5df carried) keeps the
first-launch splash from flashing before the runtime probe finishes.
Test suite (1634 tests in source, 3990 in the runtime repo) covers
resolver ordering, renderer classifiers, trace timeline shape,
compaction diff rendering, rubric parity, and the missing-key
onboarding paths.
