feat: Initialize firefrost-services monorepo structure

WHAT WAS DONE:
- Created npm workspaces configuration in root package.json
- Set up directory structure (services/, shared/, future/)
- Created @firefrost/shared package (v1.0.0)
- Added comprehensive .gitignore for Node.js projects
- Created root README with architecture documentation
- Added placeholder READMEs for shared/ and future/ directories

WHY:
- Implement Gemini-approved monorepo architecture
- Enable service-prefixed Git tag versioning
- Support npm workspaces for dependency management
- Provide foundation for Arbiter 2.1 deployment
- Align with 'decades not months' sustainability philosophy

STRUCTURE:
Root level:
- package.json (workspaces: services/*, shared)
- .gitignore (protects .env files from commits)
- README.md (comprehensive documentation)

Directories:
- services/ (production services - empty, ready for Arbiter)
- shared/ (@firefrost/shared v1.0.0 - placeholder)
- future/ (experimental services)

FILES:
- .gitignore (new, 39 lines)
- README.md (new, 242 lines)
- package.json (new, 27 lines)
- shared/package.json (new, 17 lines)
- shared/README.md (new, 47 lines)
- shared/src/index.js (new, 13 lines)
- future/README.md (new, 38 lines)

NEXT STEPS:
- Migrate Arbiter 2.1 code to services/arbiter/
- Create arbiter-v2.1.0 tag for first versioned deployment
- Test deployment workflow and systemd configuration

+
+Shared utilities and helpers for Firefrost Gaming services.
+
+## Purpose
+
+This package contains code that is used by multiple services in the firefrost-services monorepo. By centralizing common functionality here, we avoid duplication and ensure consistency across services.
+
+## Contents
+
+- **Database utilities** — Connection pooling, query helpers
+- **Discord utilities** — Embed formatting, role management helpers
+- **Pterodactyl utilities** — API wrappers, server management
+- **Logging** — Standardized logging across services
+- **Validation** — Common validation functions
+
+## Usage
+
+Services import from this package like any npm dependency:
+
+```javascript
+import { logger } from '@firefrost/shared';
+import { formatDiscordEmbed } from '@firefrost/shared';
+
+logger.info('Service started');
+```
+
+## Development
+
+To add new shared functionality:
+
+1. Create module in `src/`
+2. Export from `src/index.js`
+3. Update version in `package.json`
+4. Document in this README
+
+## Version History
+
+- **1.0.0** — Initial shared package structure
