Add CLAUDE.md with dev context and coding guidelines

Adds CLAUDE.md so Claude Code and contributors have the tech stack, key commands, and project layout at a glance when working in this repo. Links to the shared coding guidelines in the main repo rather than duplicating them here.

+# OpenDecree TypeScript SDK — Claude Context
+
+## Overview
+
+TypeScript SDK for the OpenDecree configuration service. Wraps the gRPC API with a typed
+client, field-watching subscriptions, version compatibility checks, and optional JWT rotation.
+
+## Tech Stack
+
+| Concern | Tool |
+|---------|------|
+| Language | TypeScript (strict) |
+| Runtime | Node.js 22+ |
+| Transport | @grpc/grpc-js |
+| Code generation | ts-proto via buf (Docker) |
+| Lint / format | Biome |
+| Tests | Vitest |
+| Build | tsc |
+
+## Development
+
+### Prerequisites
+
+Node.js 22+, Docker (for proto generation), npm.
+
+### Key Commands
+
+```bash
+npm run generate        # regenerate proto stubs (buf + Docker)
+npm run pre-commit      # biome check + typecheck + unit tests
+npm run test            # vitest run (unit)
+npm run test:integration # integration tests against live server
+npm run build           # tsc emit to dist/
+```
+
+### Layout
+
+```
+src/
+├── generated/    # generated proto stubs (committed)
+├── client.ts     # ConfigClient
+├── watcher.ts    # ConfigWatcher
+├── compat.ts     # server version checks
+└── ...
+test/             # unit tests
+integration/      # integration tests (live server)
+```
+
+## Coding Guidelines
+
+See [coding-guidelines.md](https://github.com/opendecree/decree/blob/main/docs/development/coding-guidelines.md)
+for the shared philosophy (vanilla principle, minimal deps) and the TypeScript-specific section
+(zero runtime deps beyond grpc-js, strict TS flags, Biome enforcement).
+
+## Conventions
+
+- Only runtime dependency: `@grpc/grpc-js`
+- Generated proto stubs committed under `src/generated/`
+- `SUPPORTED_SERVER_VERSION` generated from `package.json` via `scripts/gen-version.mjs`
