/**
 * MCP Triage workflow (leaf).
 *
 * Activated when a human resolver flags `needsTriage` in their resolution
 * payload. Dynamically adapts to ANY workflow type using available
 * MCP tools scoped by tag affinity.
 *
 * Tool ecosystem grows over time:
 * - Built-in servers: translation, vision, mcp-workflows, human-queue,
 *   workflow-compiler, db, http-fetch, file-storage, oauth, claude-code
 * - User-registered external MCP servers
 * - Compiled YAML workflows from past triage executions
 *
 * Tools are scoped by the original workflow's `tool_tags` configuration
 * (plus base tags: workflows, compiled, database). Full tool definitions
 * are cached at the module level — only lightweight IDs flow through
 * the durable execution log.
 *
 * **First entry** (no `envelope.resolver`):
 *   1. Gather upstream tasks and escalation history
 *   2. Load scoped tools (tag-filtered, cached)
 *   3. LLM agentic loop with tool IDs
 *   4. Returns `{ correctedData }` or escalates to engineer
 *
 * **Re-entry** (has `envelope.resolver` — engineer responded):
 *   1. Engineer may have installed new tools or provided guidance
 *   2. LLM re-evaluates with fresh tool inventory
 *   3. Returns `{ correctedData }` or re-escalates
