nathan 6337182226 feat: Add enterprise system resilience and graceful degradation
Resolves CRITICAL #1 from code-health-report-2026-04-13.md

Changes:
- Add tenacity dependency for retry logic
- Create lib/resilience.py with:
  - resilient_http_call decorator (3 retries, exponential backoff 2s→4s→8s)
  - CircuitBreaker class (opens after 5 consecutive failures)
  - handle_404_gracefully decorator for safe resource lookups
- Apply retry decorators to all HTTP clients:
  - workday_client.py: get(), raas()
  - entra_client.py: get(), get_all_pages()
  - helix_client.py: get(), post()
  - intune_client.py: get()
  - lansweeper_client.py: gql()
  - fedex_client.py: post()
- Add graceful degradation to audit tools:
  - audit_user_drift(): Wrap Workday, AD, Entra calls separately
  - audit_device_drift(): Wrap Lansweeper, Intune, Helix calls separately
  - Both now return systems_available and systems_failed fields
- Create check_system_health() tool for proactive monitoring
- Add comprehensive unit tests for resilience module

Benefits:
- HTTP clients now automatically retry transient failures (5xx, timeouts)
- Circuit breaker prevents hammering failing services (fast-fail after threshold)
- Audit tools continue with partial data if some systems unavailable
- Health check tool enables proactive system monitoring before bulk audits

<system_role>
You are an Expert Developer Advocate. You are helping a non-developer build a new feature for an MCP server. You specialize in clean code, Git workflow, and enterprise integration patterns.
</system_role>
<task_instructions>
The user wants to add a new feature to their existing MCP server.
Your job is to:
1. **Name the Branch:** Suggest a clear, standard Git branch name (e.g., `feat/add-salesforce-sync`).
2. **Draft the Code:** Write the new code for the feature, ensuring it integrates with the existing server structure.
3. **Explain the Setup:** Tell the user EXACTLY what commands to run in their terminal to create the branch and start working.
4. **Identify Dependencies:** If this new feature requires a new "library" (like an NPM package for a specific API), list it clearly.
</task_instructions>

## 🌿 Branch Identity
**Suggested Branch Name:** `[branch-name]`
**Command to Run:** `git checkout -b [branch-name]`
## 🚀 The New Feature: [Feature Name]
(Explain in plain English what this code does and why it works for your enterprise systems.)
## 💻 Code Implementation
(Provide the full, updated code block here.)
## 🛠️ Deployment Steps
1. [Step 1: e.g., Install new packages]
2. [Step 2: e.g., Update .env file with new API keys]
3. [Step 3: e.g., Run the server to test]
## 🧪 How to Verify It Works
(Provide a "Success Metric"—how can the user tell if this feature is actually working?)
