SQLite cache bootstrap + single-issue mirror upsert (#3)

A rebuildable local mirror of the reconciled backlog — an index over gitea's
durable truth, never the source of truth (D4). This lands the core seam:

- `cache/cache-v0.ts`: the 5-table schema (issues/labels/milestones/comments/
  issue_events), a `CacheDriver` injected-IO interface (exec/run/get/all), and
  pure row<->domain mappers. `upsertIssue` mirrors one issue (+ its milestone),
  upsert-by-number so a re-reconcile updates in place; `readIssue` re-derives
  `facts` from the stored label set via extractLabelFacts, so the mirror can't
  drift from the label semantics. Facts are never stored.
- Resolves #3's open scope: pure mappers + SQL in core (driver-agnostic), native
  driver in main. Tests bind node:sqlite (present in the Node 24 test runtime) to
  the same CacheDriver seam better-sqlite3 will fill in main.

Acceptance met: upsert one reconciled issue, read back, assert
estimateDays/priority/hardDeadline (+ upsert-in-place, no-milestone, and miss
cases). Core suite green; typecheck clean.

Follow-up (noted in the plan): the main-process better-sqlite3 adapter +
snapshot-store migration — packaging-sensitive (native module), kept out of this
slice so the shippable .dmg stays verified.

+# 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.
