Initial scaffold for AvtoAmbor parts inventory

SvelteKit 2 + Svelte 4 + adapter-node, SQLite via better-sqlite3 (WAL,
foreign keys on). Bilingual EN/Тоҷикӣ throughout, locale persisted in
localStorage.

Pages: dashboard (totals, low stock, recent movements), parts list with
search and sort, part create/edit, record movement (in/out/adjust with
smart unit-price and adjust-quantity prefill), suppliers list with
inline add.

Schema: categories, suppliers, parts (with _en/_tg name+description
columns, dirams for money), stock_movements with check on movement_type.
On-hand updates are done in JS inside a transaction with the movement
insert.

Dockerized dev: docker compose, named project, bind-mounted data/ for
DB persistence. Seed contains 6 categories, 4 suppliers, 31 realistic
parts (Lada / Nexia / Opel / Toyota bias).

+# AvtoAmbor
+
+Simple auto-parts inventory for a single shop. SvelteKit + SQLite. UI is
+bilingual (English / Тоҷикӣ).
+
+## Prerequisites
+
+- Docker + Docker Compose
+
+Everything else (Node, npm, native build tools for `better-sqlite3`) runs
+inside the container.
+
+## Quickstart
+
+```sh
+make install     # install dependencies inside the container
+make db-init     # create data/avtoambor.db with schema + seed
+make run         # dev server at http://localhost:5173
+```
+
+`make help` lists every target.
+
+## Production
+
+Build with `make build`, copy the `build/` directory plus `node_modules` and
+`data/avtoambor.db` to the Windows host, then run:
+
+```sh
+node build/index.js
+```
+
+The server listens on port 3000 by default. Open `http://localhost:3000` in
+the browser on that machine.
+
+## Data
+
+The SQLite database lives at `data/avtoambor.db`. The `data/` directory is
+gitignored and bind-mounted into the container, so the DB file persists on
+the host.
+
+- `make db-init`  — create the DB if it doesn't exist (does nothing otherwise).
+- `make db-reset` — delete and recreate the DB (asks for confirmation).
