feat: add core application stack — hardware, scheduling, API, and UI

[ng]

Summary

Foundational implementation of the SleepyPod core stack, built on top of the existing project scaffolding.

• DB: Migrates from Prisma to Drizzle ORM with better-sqlite3; adds 11-table SQLite schema covering device config, schedules, biometrics, and runtime state
• Hardware: Type-safe hardware abstraction layer over the dac.sock Unix socket — sequential command queue, response parser, Pod 3/4/5 support, temperature conversion utilities
• API: Full tRPC router suite — device control, settings, schedule CRUD, biometrics queries; all inputs validated with Zod
• Scheduler: node-schedule-backed job manager for temperature, power, alarm, prime, and reboot jobs; timezone-aware, database-driven, auto-reloads on config changes
• UI: Next.js pages for pod control (/control), settings (/settings), and schedule management (/schedules); mobile-responsive navigation; tRPC-integrated with 5s auto-refresh

Test plan

• pnpm tsc passes with no errors
• pnpm lint passes
• pnpm db:migrate runs without errors on a fresh DB
• /control page renders and reflects live hardware status when pod is connected
• /settings page saves timezone and side name changes correctly
• /schedules page lists and deletes schedules correctly
• Scheduler loads jobs on startup and logs upcoming invocations
• POWER_ON / POWER_OFF / TEMPERATURE / ALARM jobs execute against hardware

📝 Walkthrough

Walkthrough

Implements a complete smart pod control application with Drizzle ORM backend, hardware abstraction layer, job scheduling system, tRPC API routers, and React UI pages. Replaces Prisma with Drizzle, adds device communication protocols, automated scheduling, and frontend interfaces for temperature control, settings, and schedule management.

Changes

Cohort / File(s)	Summary
Database Migration (Prisma → Drizzle) drizzle.config.ts, src/db/index.ts, src/db/migrate.ts, src/db/schema.ts, src/db/migrations/*, prisma.config.ts, prisma/schema.prisma, src/lib/prisma.ts	Replaces Prisma ORM with Drizzle ORM using better-sqlite3. Adds comprehensive schema with device settings, side settings, device state, schedules (temperature/power/alarm), biometrics (vitals/movement/sleep), system health, and tap gesture tables. Includes migration files, graceful shutdown handlers, and default data seeding.
Hardware Abstraction Layer src/hardware/client.ts, src/hardware/types.ts, src/hardware/socketClient.ts, src/hardware/messageStream.ts, src/hardware/responseParser.ts, src/hardware/sequentialQueue.ts, src/hardware/index.ts	Adds complete hardware communication layer for pod control. Includes socket-based client with reconnection logic, message streaming with timeout handling, CBOR response parsing, sequential command queuing to prevent race conditions, and comprehensive type definitions for hardware commands, device status, alarms, gestures, and error handling.
Scheduler System src/scheduler/scheduler.ts, src/scheduler/jobManager.ts, src/scheduler/types.ts, src/scheduler/index.ts	Implements timezone-aware job scheduling using node-schedule. Scheduler manages cron-based jobs with event emission; JobManager loads schedules from database and orchestrates hardware operations (temperature, power, alarms, priming, reboots). Supports reload/timezone updates and graceful shutdown.
tRPC API Routers src/server/routers/device.ts, src/server/routers/settings.ts, src/server/routers/schedules.ts, src/server/routers/biometrics.ts, src/server/routers/app.ts	Exposes tRPC procedures for device control (status, temperature, power, alarms, priming), device/side settings management with timezone/unit configuration, CRUD operations for three schedule types (temperature/power/alarm) with day-based querying, and biometrics data retrieval (sleep records, vitals, movement) with date filtering and aggregation.
Frontend Pages & Components app/[lang]/control/page.tsx, app/[lang]/page.tsx, app/[lang]/schedules/page.tsx, app/[lang]/settings/page.tsx, src/components/Navigation/Navigation.tsx, src/components/SideSelector/SideSelector.tsx, src/components/TemperatureControl/TemperatureControl.tsx	Adds responsive React pages with real-time device control UI (two-panel temperature/power/priming), home page with navigation cards, schedules management with temperature/power/alarm CRUD, and settings for device/side configuration. Includes responsive navigation bar and sidebar components with active link highlighting.
Utility Modules & Config src/lib/tempUtils.ts, .claude/commands/pr-describe.md, package.json	Adds temperature conversion and formatting utilities (Fahrenheit/Celsius, Eight Sleep scale mapping, trend detection). Updates package.json: removes Prisma dependencies, adds Drizzle ORM, node-schedule, and supporting libraries (binary-split, cbor-x); updates dev scripts for database operations. Includes PR documentation guide.

Poem

🐰 Whiskers twitch with pod control glee,
Drizzle flowing where Prisma used to be,
Schedules hop and temperatures align,
Socket chatter keeps the device so fine,
A rabbit's dream: hardware, API, and UI shine! ✨
