Plan 15 — Packaging (electron-builder + sidecar bundle + signing)

[carlomigueldy]

Plan file: docs/superpowers/plans/2026-05-23-plan-15-packaging.md
Tag at close: v0.0.15-plan-15
Depends on: Plan 14 (UI complete)

Goal

Produce distributable installers for macOS (.dmg), Windows (.exe via NSIS), and Linux (.AppImage + .deb). Bundle the dycoded daemon binary, all built-in adapters, and the prebuilt node-pty / better-sqlite3 native modules. Sign + notarize on macOS, sign on Windows. Wire up release.yml GitHub Actions workflow to publish on tag push.

Deliverable

• electron-builder.yml + entitlements + native rebuild script.
• macOS hardened runtime + notarization; Windows code signing; Linux AppImage + deb.
• .github/workflows/release.yml — matrix build across 3 OSes, publishes to GH Releases.
• Auto-update foundation wired but disabled until v1.0.
• F96–F101.

Out of scope (deferred to later plans)

• Auto-update channel enablement → v1.0
• Remote crash reporting → v1.1 (opt-in)
• Microsoft Store / Mac App Store → out of scope for v1

Workflow

• Branch from main via superpowers:using-git-worktrees: feat/plan-15-packaging.
• One PR closes this issue — include Closes #<this issue's number> in the PR description.
• Update docs/superpowers/plans/README.md to move this plan from "not started" to "shipped" in the same PR.
• Final step is the close-out commit and git tag v0.0.15-plan-15.
• All 5 quality gates apply (CONTRIBUTING.md).
