xingyue 484ed520cd feat(dashboard): switch graph layout from Dagre to ELK
What: Replace Dagre layout engine with ELK (Eclipse Layout Kernel) for
workflow graph visualization in the dashboard.

Why: Dagre lacks support for edge label placement and orthogonal edge
routing, causing condition labels to overlap with nodes. ELK provides
proper label positioning, better edge routing, and more compact layouts.

Changes:
- packages/workflow-dashboard/package.json: add elkjs dependency
- packages/workflow-dashboard/src/components/workflow-graph/use-layout.ts:
  rewrite layout from Dagre to async ELK with layered algorithm,
  orthogonal routing, reduced spacing for compactness
- packages/workflow-dashboard/src/components/workflow-graph/condition-edge.tsx:
  use ELK-computed label positions, show all labels including FALLBACK,
  switch to getSmoothStepPath for all edges
- packages/workflow-dashboard/src/components/workflow-graph/workflow-graph.tsx:
  wrap in ReactFlowProvider, add fitView on async layout change,
  key-based remount for layout stability
- packages/workflow-dashboard/src/components/workflow-list.tsx:
  left-right layout (info left, graph right), fix toggleExpanded
  React 18 batching bug, increase graph container height

@uncaged/workflow

A workflow engine that executes single-file ESM bundles. Each workflow is a self-contained .esm.js file identified by its XXH64 hash (Crockford Base32).

Core Concepts

Concept Description
Workflow A single-file ESM module exporting run (workflow function) and descriptor (metadata). Identified by its XXH64 hash.
Bundle The physical .esm.js file stored in ~/.uncaged/workflow/bundles/.
Thread A single execution of a workflow, identified by a ULID. CAS-backed chain plus threads.json / history/*.jsonl; .info.jsonl for debug logs.
Role A named actor within a workflow. Each role produces output with typed meta. Roles live inside template packages (src/roles/).
Registry workflow.yaml — maps workflow names to current/historical bundle hashes.
CAS Content-Addressed Storage — bundles are immutable and addressed by hash.

Monorepo Packages

Managed with bun workspace using the workspace:* protocol.

Quick Start

# Install dependencies
bun install

# Build all packages
bun run build

# Register a workflow bundle
uncaged-workflow workflow add solve-issue dist/packages/workflow-template-solve-issue/solve-issue.esm.js

# Run a workflow
uncaged-workflow run solve-issue --prompt "Fix bug #42"

CLI Usage

uncaged-workflow                   # Print full command usage (exits with status 1)
uncaged-workflow workflow list     # List registered workflows
uncaged-workflow run <name>        # Start a workflow thread
uncaged-workflow thread list       # List all threads
uncaged-workflow thread show <id>  # Inspect a thread
uncaged-workflow skill             # Agent-consumable reference docs

Run uncaged-workflow with no arguments to print usage, or uncaged-workflow skill cli for the full CLI skill reference.

Development

bun run check    # Biome lint + format check
bun run format   # Auto-format with Biome
bun test         # Run tests
