Scaffold CommiTea: yarn workspaces, Electron shell, core label schema, design system

- apps/desktop: electron-vite + React + Tailwind mapped onto design tokens
  (preflight off; tokens/base.css owns the reset); boots to a Reginald
  placeholder proving fonts/tokens/core wiring
- packages/core: pure TS; gitea label schema (est/*, p/*, deadline/hard)
  with pessimistic conflict resolution + 15 unit tests
- docs/design: full design handoff (tokens, 16 component contracts,
  interactive 14-screen prototype, Reginald voice rules)
- docs/PLAN.md: product plan (purity rule, pm-state repo, deterministic
  scheduler + Monte Carlo, directive log)
- Deliberate deviation from novelpad stack: no ElectricSQL/PGlite — local
  store is a rebuildable cache over gitea REST/webhooks (better-sqlite3
  in main process, arriving in P1)

+# CommiTea app — UI kit
+
+High-fidelity recreation of the CommiTea Electron app (one window). Built from the product plan (`uploads/commitea.md`); no production UI existed yet, so this kit **is** the reference design.
+
+Surfaces (per the plan's UI section):
+
+- **Onboarding / first run** ("First run" in the nav) — full-window takeover, no rail or chat: Reginald introduces himself → connect Gitea (test connection) → choose the managed repo → propose-approve bootstrap (pm-state sidecar, label schema, webhook) ending at "Start a capture".
+- **Standup** — the morning ritual as a typeset letter from Reginald: overnight drift report (with mono consequence deltas), today's plan per person, and the stale-blocker nag. Sections settle in once, 320ms, reduced-motion-safe.
+- **Morning service (Focus)** — Now/Next/Later focus cards with the scheduler's pick and Reginald's one-line rationale; burn-up chart with Monte Carlo forecast cone.
+- **Board** — kanban over the inferred lifecycle (diagnosis → triage → steeping → review → done), with Gantt and Dependencies drill-in tabs: the Gantt shows scheduler-derived bars with 80% forecast tails and Beta's landing band; Dependencies is a layered DAG with the critical path in spruce.
+- **Issue detail** (click any issue anywhere) — the purity rule made visible: human intent from gitea on the left (description, comments, composer that "writes to gitea, as you"), machine-derived sidecar on the right (inferred lifecycle timeline from git events, per-issue forecast, dependencies) with the provenance note "Lives in pm-state. Your repo never sees any of it."
+- **Inbox** — the bell Reginald only rings when it matters: drift, mentions, nags, reviews, system events — day-grouped, filter tabs, unread dots with a live count in the rail; rows navigate to the issue or directive concerned. "Nothing here rings twice."
+- **Directives** — the append-only ledger (who/when/what/why) plus the consequence diff: scheduler re-runs after a directive and Reginald presents before → after deltas for approval ("Make it so" / Amend / Withdraw). Also reachable from the history icon in Reginald's panel.
+- **Runway** — capacity vs milestone dates; forecast ranges, never point dates. Its calibration card drills into the **Calibration report**: estimate-vs-actual scatter ("the shape of hope") with honest-diagonal and fitted ×1.18 line, bias by estimate label, per-person bias, and the effect on forecast bands. Milestone rows drill into **Milestone detail**: stats strip (scope / done / forecast / drift), burn-up cone, and the issue list grouped by lifecycle state.
+- **Capture** — the plan's headline goal: braindump → interview → approved ticket set in under 2:00, with a running clock. Reginald asks only what he can't infer; drafts build in "the tray" as you answer; review shows the consequence (cone shift) before "Approve all"; filing touches labels only.
+- **Reginald's panel** (right side, always present) — chat is the write-path; UI is the read-path. Reginald speaks in upright Caslon serif.
+
+- **States** (nav, bottom) — gallery of empty & trouble states as wired in the app: empty pot / nothing scheduled / no directives / search miss; gitea-unreachable banner, model-offline chat state, webhook poll-fallback, failed first reconcile. Two are live: board search shows the real empty state, and clicking the rail's connection dot toggles offline mode (banner app-wide, Reginald queues writes, composer disabled).
+
+Interactive: nav switching, issue click → detail page, chat replies (canned), light/dark theme toggle, offline simulation.
