feat(go-crm): full auth, routing, middleware, and supporting infra

- Add auth handlers (signup, login, logout, account management) with bcrypt
- Add client, customer, service, scheduling, payment, question, answer handlers
- Add dashboard, monthly report, and lead pipeline pages
- Add UTF-8 middleware to force charset on HTML responses
- Add config package with env-based overrides for DB path, secrets, endpoints
- Add parser package for WhatsApp message ingestion
- Add clean-arch layers: pkg/domain, pkg/repo, pkg/usecase for leads
- Add cmd/migrate utility for DB migrations
- Add Makefile, README, run-tests.sh, and dev scripts
- Update docker-compose.yml with memory limits
- Update .air.toml to exclude DB files and stop on errors
- Update whatsapp-sync dependencies and add src/index.js entrypoint
- Add whatsme standalone WhatsApp reader app (source only)
- Untrack .opencode-sandbox/data/go-crm.db from git history
- Expand root .gitignore: ngrok, tmp dirs, sandbox DBs, compiled binaries

go build -o go-crm main.go # build binary
./go-crm # run binary
go mod tidy # clean go.mod/go.sum
go mod download # deps
go mod tidy # clean go.mod/go.sum

```
### whatsapp-reader
```bash
cd apps/whatsapp-reader
node index.js # main script
node sync.js # sync script
node index.js # main script
node sync.js # sync script
# no test script
```
### timesfm-forecast
```bash
cd apps/timesfm-forecast
uv venv && source .venv/bin/activate
uv pip install -e .
ruff check . # lint (dev dep)
timesfm-app # run Streamlit app
uv venv && source .venv/bin/activate # create + activate venv
uv pip install -e . # install package
timesfm-app # run Streamlit app
# See apps/timesfm-forecast/README.md for CUDA/CPU wheel guidance

## Code Style Guidelines
## Important Quirks
### TypeScript
### WhatsApp auth sessions
- `.wwebjs_auth/` directories store session state — do not commit these
- `whatsapp-sync` uses `better-sqlite3` for persistence
- `whatsapp-crm` browser-side uses `sql.js` (WebAssembly, no native deps)
### go-crm auth
- `X-Internal-Secret` header required on requests (value: `internal-secret`)
- WhatsApp connector init URL: `http://localhost:8080`
### Docker
```bash
docker compose up whatsapp-crm # CRM only
docker compose --profile sync up # CRM + sync
docker compose --profile test up # test runner
```
### go-crm hot-reload
- Uses `air` (not `go run`) — configured in `.air.toml`
- Build excludes `_test.go` and `vendor/`, `tmp/`, `assets/`
### TypeScript config (whatsapp-crm, whatsapp-sync)
- `strict: true` in tsconfig.json
- Explicit types for params + return values
- `interface` for objects, `type` for unions/aliases
- Path alias `@/*` maps to `src/*`
```typescript
interface Contact {
id: number
name: string
stage: Stage
}
function getContactById(id: number): Contact | null
```
### Imports
- Path alias `@/*` (tsconfig.json)
- Order: external → internal → relative
- Group: React imports → other imports → types → components
```typescript
import { useState, useMemo } from 'react'
import { Stage, STAGES, Contact } from '@/lib/types'
import { ContactCard } from '@/components/ContactCard'
```
### Naming
- **Components**: PascalCase (`KanbanBoard`, `ContactCard`)
- **Files**: PascalCase (`.tsx`), camelCase (`.ts`)
- **Interfaces/Types**: PascalCase
- **Constants**: UPPER_SNAKE_CASE
- **Hooks**: camelCase + `use` prefix
- **Booleans**: `is`/`has`/`should` prefix
### Error Handling
- Zod for input validation + react-hook-form
- Wrap async in try/catch
- Return proper HTTP status codes
```typescript
export async function POST(request: Request) {
try {
const body = await request.json()
const validated = CreateContactInput.parse(body)
} catch (error) {
if (error instanceof ZodError) {
return Response.json({ error: error.errors }, { status: 400 })
}
return Response.json({ error: 'Internal server error' }, { status: 500 })
}
}
```
### Component Structure
- `'use client'` directive for client-side
- Destructure props, explicit typing
- Keep components focused, small
- Extract reusable logic to custom hooks
```typescript
'use client'
interface Props {
contacts: Contact[]
onContactClick: (contact: Contact) => void
}
export default function ComponentName({ contacts, onContactClick }: Props) {
const [state, setState] = useState(false)
return <div>{/* JSX */}</div>
}
```
### Database (sql.js)
- Zod schemas for table definitions
- Validate data before insert/update
- Use transactions for multi-step ops
### Testing
- Test files: `tests/*.test.ts` or `*.test.tsx`
- `@testing-library/react` for component tests
- `@testing-library/user-event` for interactions
- AAA pattern: Arrange, Act, Assert
```typescript
test('should update contact stage', async () => {
const user = userEvent.setup()
render(<KanbanBoard {...props} />)
await user.click(screen.getByText('Move to Next Stage'))
expect(onStageChange).toHaveBeenCalledWith(1, 'DECIDINDO')
})
```
### CSS / Styling
- CSS modules or global CSS
- BEM-like: `block-element--modifier`
- Co-locate styles when possible
### Git
- Meaningful commit messages
- Branch naming: `feature/description` or `fix/description`
- Run `npm run lint` + `npm run test` before commit
### Testing mocks
- `whatsapp-sync` has manual mocks for `qrcode-terminal` and `whatsapp-web.js` in `tests/__mocks__/`

## Important Notes
## What to Avoid
- whatsapp-crm: Next.js 14 App Router
- Database: sql.js (WebAssembly SQLite), runs in browser
- Auth: WhatsApp Web.js QR code scanning
- STAGES constant: Kanban pipeline (defined in `src/lib/types.ts`)
- Do not use `go run main.go` for development — use `air`
- Do not commit `.wwebjs_auth/` or `.wwebjs_cache/` directories
- Do not change hardcoded DB paths in `main.go`
- The `data-engineering/` projects are standalone — no shared build or test commands
