fix(desktop): run the macOS Host from the helper so it takes no Dock tile

[elkaix]

Related Issue

No issue — reported directly: a second, unnamed icon appears in the macOS Dock whenever the desktop app is running.

Problem

The packaged app starts its Host by re-executing its own binary
(Pythinker.app/Contents/MacOS/Pythinker). macOS registers that child with
LaunchServices as a second foreground application under the same bundle id, so it takes a
Dock tile of its own. A bare executable has no icon, so the tile renders with the generic
Unix-executable artwork next to the real app icon.

ELECTRON_RUN_AS_NODE=1 is already set and is not the missing piece: it stops the child from
becoming a browser process, but it does not affect LaunchServices registration.

Observed on the installed 0.1.5 build:

90) "pythinker-code"  bundleID="com.pythinker.desktop"
    executable path="/Applications/Pythinker.app/Contents/MacOS/Pythinker"
    pid = 83782   type="Foreground"
    parentASN="Pythinker" (inferred)

What changed

resolveHostExecutable picks the bundled Electron helper
(Contents/Frameworks/<name> Helper.app) as the Host runtime on macOS. The helper declares
LSUIElement, so it registers as a UI element rather than a foreground app and takes no Dock
tile, while running the identical Node runtime. It falls back to process.execPath when the
bundle ships no matching helper, and non-macOS platforms are returned unchanged.

Verified against the installed bundle:

same script via the app binary → type="Foreground"   (Dock tile)
same script via the helper     → type="UIElement"    (no Dock tile)
helper as a Node runtime       → node v24.18.1, electron 43.4.0

Summary by CodeRabbit

• Bug Fixes

  • Fixed a macOS Dock issue that could display a second unnamed Pythinker icon while the app was running.
  • Improved packaged desktop startup behavior across macOS, Windows, and Linux.

• Changes

  • Removed managed Kimi update checks, marketplace defaults, official plugin badges, tips, and sign-up links.
  • Kimi remains available as a model provider through OAuth or an API key; marketplace access requires a configured marketplace URL.
  • Updated activity card wording to “subagent.”

📝 Walkthrough

Walkthrough

The desktop app now resolves its packaged host executable through a macOS-aware helper. Tests cover helper selection and fallback behavior. Three changesets record the desktop patch, code package release classification, and terminology update.

Changes

Desktop runtime

Layer / File(s)	Summary
Host executable resolution apps/desktop/src/host-supervisor.ts	Adds resolveHostExecutable, which selects the bundled macOS helper when present and preserves the supplied executable otherwise.
Startup wiring and validation apps/desktop/src/main.ts, apps/desktop/tests/host-supervisor.spec.ts	Packaged startup uses the resolver. Tests cover macOS selection, fallback behavior, and unchanged Windows and Linux paths.

Release metadata

Layer / File(s)	Summary
Release changeset updates .changeset/desktop-dock-tile.md, .changeset/remove-managed-kimi-endpoints.md, .changeset/subagent-execution-inspector.md	Adds the desktop patch changeset, raises the code package release level to major, and updates “sub agent” to “subagent”.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to d9520

The PR changes macOS host launching to use the bundled helper, preventing the duplicate Dock tile. No actionable merge-blocking risk remains.
