Phase C: package as an unsigned macOS .dmg (electron-builder)

Adds shareable desktop packaging so the app can be handed to teammates.

- electron-builder@25 + electron-builder.yml: appId io.stephenmann.commitea,
  productName CommiTea, icon from the logo (build/icon.png, 1024²), macOS dmg
  targets for arm64 + x64. Ships only out/** (electron-vite already bundles
  renderer/preload/main with core + react inlined), npmRebuild off,
  electronVersion pinned to 34.5.8 (workspace hoisting defeats auto-detect).
- Unsigned by decision: mac.identity null, hardenedRuntime off. electron-builder
  ad-hoc signs so arm64 runs; not notarized — teammates right-click → Open once.
- Scripts: `yarn pack` (--dir sanity build), `yarn dist` (both dmgs). package.json
  gains version/author/description (required by electron-builder).
- README.md: dev/build/package commands + the Gatekeeper install step.

Verified: packaged arm64 app boots from a fresh profile (lands on onboarding);
`yarn dist` produced CommiTea-0.1.0-arm64.dmg (98M) and CommiTea-0.1.0.dmg (x64,
102M), each mounting with a drag-to-Applications layout.

+# CommiTea (desktop)
+
+An AI project manager for Gitea, as an Electron desktop app. The token stays in
+the main process (OS keychain via `safeStorage`); the renderer never sees it.
+
+## Develop
+
+```bash
+yarn dev          # electron-vite dev, HMR renderer + main (logs → desktop.log)
+yarn typecheck
+yarn e2e          # builds, then Playwright against the built main (fixtures/demo)
+```
+
+For a live pass against a real Gitea, put a token in `.env.local`
+(`GITEA_TOKEN=…`) and run `GITEA_LIVE=1 yarn e2e live-onboarding`.
+
+## Package (shareable macOS .dmg)
+
+```bash
+yarn pack         # unpacked .app for the host arch (fast sanity check) → dist/
+yarn dist         # arm64 + x64 .dmg → dist/CommiTea-<version>[-arm64].dmg
+```
+
+Config is `electron-builder.yml`. Builds are **unsigned** (no Apple certs, by
+decision) — electron-builder ad-hoc signs so the app can run, but it is not
+notarized. Bump `version` in `package.json` for a new release; keep
+`electronVersion` in `electron-builder.yml` in sync with the `electron`
+devDependency.
+
+### Installing a shared build (teammates)
+
+macOS Gatekeeper blocks unsigned apps on first launch. To open:
+
+1. Open the `.dmg` and drag **CommiTea** to **Applications**.
+2. In Applications, **right-click CommiTea → Open**, then confirm **Open** in the
+   dialog. (Double-clicking the first time just shows "cannot be opened".)
+3. It opens to the connection screen — enter your Gitea base URL, `owner/repo`,
+   and a personal access token (repo scope). Each teammate uses their own token,
+   so activity is attributed correctly. A model URL is optional; chat is disabled
+   until one is configured, everything else works without it.
+
+Grab the `-arm64` dmg on Apple Silicon, the plain one on Intel.
