Rename project from Gooti to Plebian Signer and add Claude Code config

- Rename all gooti-* files to plebian-signer-* across Chrome and Firefox
- Rename GootiMetaHandler to SignerMetaHandler in common library
- Update all references to use new naming convention
- Add CLAUDE.md with project build/architecture documentation
- Add Claude Code release command tailored for this npm/Angular project
- Add NWC-IMPLEMENTATION.md design document
- Add Claude skills for nostr, typescript, react, svelte, and applesauce libs
- Update README and various component templates with new branding

+
+## Project Overview
+
+Plebian Signer is a browser extension for managing multiple Nostr identities and signing events without exposing private keys to web applications. It implements NIP-07 (window.nostr interface) with support for NIP-04 and NIP-44 encryption.
+
+## Build Commands
+
+```bash
+npm ci                    # Install dependencies
+npm run build:chrome      # Build Chrome extension (outputs to dist/chrome)
+npm run build:firefox     # Build Firefox extension (outputs to dist/firefox)
+npm run watch:chrome      # Development build with watch mode for Chrome
+npm run watch:firefox     # Development build with watch mode for Firefox
+npm test                  # Run unit tests with Karma
+npm run lint              # Run ESLint
+```
+
+## Architecture
+
+### Monorepo Structure
+
+This is an Angular CLI monorepo with three projects:
+
+- **projects/chrome**: Chrome extension (MV3)
+- **projects/firefox**: Firefox extension
+- **projects/common**: Shared Angular library used by both extensions
+
+### Extension Architecture
+
+The extension follows a three-layer communication model:
+
+1. **Content Script** (`plebian-signer-content-script.ts`): Injected into web pages, bridges messages between page scripts and the background service worker
+
+2. **Injected Script** (`plebian-signer-extension.ts`): Injected into page context, exposes `window.nostr` API to web applications
+
+3. **Background Service Worker** (`background.ts`): Handles NIP-07 requests, manages permissions, performs cryptographic operations
+
+Message flow: Web App → `window.nostr` → Content Script → Background → Content Script → Web App
+
+### Storage Layers
+
+- **BrowserSyncHandler**: Encrypted vault data synced across browser instances (or local-only based on user preference)
+- **BrowserSessionHandler**: Session-scoped decrypted data (unlocked vault state)
+- **SignerMetaHandler**: Extension metadata (sync flow preference)
+
+Each browser (Chrome/Firefox) has its own handler implementations in `projects/{browser}/src/app/common/data/`.
+
+### Custom Webpack Build
+
+Both extensions use `@angular-builders/custom-webpack` to bundle additional entry points beyond the main Angular app:
+- `background.ts` - Service worker
+- `plebian-signer-extension.ts` - Page-injected script
+- `plebian-signer-content-script.ts` - Content script
+- `prompt.ts` - Permission prompt popup
+- `options.ts` - Extension options page
+
+### Common Library
+
+The `@common` import alias resolves to `projects/common/src/public-api.ts`. Key exports:
+- `StorageService`: Central data management with encryption/decryption
+- `CryptoHelper`, `NostrHelper`: Cryptographic utilities
+- Shared Angular components and pipes
+
+## Testing Extensions Locally
+
+**Chrome:**
+1. Navigate to `chrome://extensions`
+2. Enable "Developer mode"
+3. Click "Load unpacked"
+4. Select `dist/chrome`
+
+**Firefox:**
+1. Navigate to `about:debugging`
+2. Click "This Firefox"
+3. Click "Load Temporary Add-on..."
+4. Select a file in `dist/firefox`
+
+## NIP-07 Methods Implemented
+
+- `getPublicKey()` - Return public key
+- `signEvent(event)` - Sign Nostr event
+- `getRelays()` - Get configured relays
+- `nip04.encrypt/decrypt` - NIP-04 encryption
+- `nip44.encrypt/decrypt` - NIP-44 encryption
