feat: L'Ami Fiduciaire V1.0.0 — full codebase with Story 0.1 complete

Initial commit of the L'Ami Fiduciaire SaaS platform built on Laravel 12,
Vue 3, Inertia.js 2, and Tailwind CSS 4.

Story 0.1 (rename folders to declarations in database) is implemented and
code-reviewed: migration, rollback, and 6 Pest tests all passing.

+# Subagent 4D: Scalability NFR Assessment
+
+## SUBAGENT CONTEXT
+
+This is an **isolated subagent** running in parallel with other NFR domain assessments.
+
+**Your task:** Assess SCALABILITY NFR domain only.
+
+---
+
+## SUBAGENT TASK
+
+### 1. Scalability Assessment Categories
+
+**A) Horizontal Scaling:**
+
+- Stateless architecture
+- Load balancer configuration
+- Container orchestration (K8s)
+- Auto-scaling policies
+
+**B) Vertical Scaling:**
+
+- Resource allocation
+- Database size limits
+- Memory management
+- CPU optimization
+
+**C) Data Scaling:**
+
+- Database partitioning/sharding
+- Read replicas
+- Caching layers
+- Data archival strategy
+
+**D) Traffic Handling:**
+
+- CDN for static assets
+- Rate limiting
+- Queue systems for async work
+- WebSocket scaling
