feat(desktop): DSH Electron desktop shell — harness internals visualized

Browse Source 
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.

# mock-llm/echo-tool ts files via `../../deepseek-harness-dev/examples/
# echo-agent/…`. In the OFFICIAL repo layout (deepseek-harness with this
# shell copied under examples/desktop/) those same ts files live at
# `../../echo-agent/…` — no sibling, they're siblings-of-desktop inside
# the monorepo. Rewriting at assemble time keeps the source yml usable
# for local dev AND ships a working shape to the released tree.
#
# BSD sed (default on macOS) has no `-i ''`-vs-`-i` compat trick that
# works both places, so we do stream-in / stream-out to a temp file per
# leaf — portable, boring.

// batch-c-08 Output panel Fields card drilling into a tool_result row +

// batch-c-09 Input panel message row exposing its own Fields subtree —
// parity with Output rows so system prompts with

// metadata are recursively reachable from the Input side too.

// payload-controls overlap regression probe (2026-07-18 delta).
//
// Boots a fresh isolated Electron instance, injects tool blocks with a
// long meta suffix ("(content · meta · isError · error · durationMs)"),
// opens the JSON drawer, then asserts via getBoundingClientRect() that
// the button cluster (pretty ⇅ raw · copy · download) does NOT overlap
// the label / meta text at either width.
//
// Four payload-controls mount points get exercised — matches the shipped
// (merged) fix from da779ac (`fix/ui-hotfix-drawer-overlap` -> 9743db1):
// A) inline tool-block args renderer.js:1226 → `.tool-block-label-row`
// B) inline tool-block result renderer.js:1249 → `.tool-block-label-row`
// C) tool-json-drawer sections tool-cards.js:663 → `.tool-json-section-controls[data-drawer-controls]`
// D) trace-detail Render=JSON trace-detail-pane.js:1512 → `.trace-detail-json-panel`
// (no-op verify — mount is flex-column,
// controls right-anchor via margin-left)
//
// Runs the app under a private user-data dir + dedicated CDP port so it
// never collides with the user's own Electron. Kills the child on exit.
//
// Usage: `pnpm exec node scripts/qa-overlap-fix-probe.mjs [outDir]`.
// Requires the electron binary at `node_modules/.bin/electron`. When run
// in a worktree that has never had `pnpm install` executed there, either
// (a) run `pnpm install` locally, or (b) symlink `node_modules` in from
// the primary checkout — see docs/qa-overlap-fix/README.md.
