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.

+# Step 3: Map Criteria to Tests
+
+## STEP GOAL
+
+Create the traceability matrix linking requirements to tests.
+
+## MANDATORY EXECUTION RULES
+
+- 📖 Read the entire step file before acting
+- ✅ Speak in `{communication_language}`
+
+---
+
+## EXECUTION PROTOCOLS:
+
+- 🎯 Follow the MANDATORY SEQUENCE exactly
+- 💾 Record outputs before proceeding
+- 📖 Load the next step only when instructed
+
+## CONTEXT BOUNDARIES:
+
+- Available context: config, loaded artifacts, and knowledge fragments
+- Focus: this step's goal only
+- Limits: do not execute future steps
+- Dependencies: prior steps' outputs (if any)
+
+## MANDATORY SEQUENCE
+
+**CRITICAL:** Follow this sequence exactly. Do not skip, reorder, or improvise.
+
+## 1. Build Matrix
+
+For each acceptance criterion:
+
+- Map to matching tests
+- Mark coverage status: FULL / PARTIAL / NONE / UNIT-ONLY / INTEGRATION-ONLY
+- Record test level and priority
+- Record heuristic signals:
+  - Endpoint coverage present/missing (for API-impacting criteria)
+  - Auth/authz coverage present/missing (positive and negative paths)
+  - Error-path coverage present/missing (validation, timeout, network/server failures)
+
+---
+
+## 2. Validate Coverage Logic
+
+Ensure:
+
+- P0/P1 criteria have coverage
+- No duplicate coverage across levels without justification
+- Criteria are not happy-path-only when requirements imply error handling
+- API criteria are not marked FULL if endpoint-level checks are missing
+- Auth/authz criteria include at least one denied/invalid-path test where applicable
+
+---
+
+### 3. Save Progress
+
+**Save this step's accumulated work to `{outputFile}`.**
+
+- **If `{outputFile}` does not exist** (first save), create it using the workflow template (if available) with YAML frontmatter:
+
+  ```yaml
+  ---
+  stepsCompleted: ['step-03-map-criteria']
+  lastStep: 'step-03-map-criteria'
+  lastSaved: '{date}'
+  ---
+  ```
+
+  Then write this step's output below the frontmatter.
+
+- **If `{outputFile}` already exists**, update:
+  - Add `'step-03-map-criteria'` to `stepsCompleted` array (only if not already present)
+  - Set `lastStep: 'step-03-map-criteria'`
+  - Set `lastSaved: '{date}'`
+  - Append this step's output to the appropriate section of the document.
+
+Load next step: `{nextStepFile}`
+
+## 🚨 SYSTEM SUCCESS/FAILURE METRICS:
+
+### ✅ SUCCESS:
+
+- Step completed in full with required outputs
+
+### ❌ SYSTEM FAILURE:
+
+- Skipped sequence steps or missing outputs
+  **Master Rule:** Skipping steps is FORBIDDEN.
