root be7436b6f0 Diverse scenario engine: 15 weighted staffing situations replace crisis-every-refresh
Simulation now uses weighted random selection across 4 priority tiers:
- Urgent (walkoff, quarantine, no-show), High (new client, cert expiry, expansion),
  Medium (recurring, seasonal, medical leave, cross-train), Low (future, exploratory)
- Color-coded scenario banners on ALL contracts, not just urgent
- Each scenario carries context (note) + recommended action

/**
* Lakehouse MCP Server — bridges local LLMs to the data substrate.
*
* Tools:
* - search_workers: hybrid SQL+vector (the core fix)
* - query_sql: analytical SQL on any dataset
* - match_contract: find workers for a job order
* - get_worker: single worker by ID
* - rag_question: full RAG pipeline
* - log_success: record what worked → playbook DB
* - get_playbooks: retrieve past successes
* - swap_profile: hot-swap model + data context
* - vram_status: GPU introspection

<div style="color:#94a3b8;font-size:12px">Upload a spreadsheet with names, phone numbers, and roles. That's enough. The system organizes them by role and location so you can find who you need faster than scrolling a list. No scores, no metrics — just organized contacts.</div>
</div>

<div style="color:#c4b5fd;font-size:13px;line-height:1.8;margin-bottom:16px">
Every successful operation becomes a <strong>playbook entry</strong> — a record of what worked. When a similar situation comes up, the system doesn't start from scratch. It checks: "Last time we needed welders in Ohio, here's who we placed and how it went."
</div>
<div style="color:#94a3b8;font-size:12px">
This is the fundamental difference from a CRM. A CRM stores data. This system stores <em>decisions and outcomes</em>. Over time, it becomes an institutional memory that doesn't retire, doesn't forget, and doesn't depend on one person knowing everything. Your senior staff's expertise becomes embedded in the system — not replacing them, but making sure what they know is available even when they're not in the room.
