glm-5.1 466b121f77 decompose architecture into 38 atomic tasks across 12 parallel generations

Decompose the reviewed architecture specs into taskgraph-managed tasks:
- 2 setup tasks (project init, test infrastructure)
- 4 schema tasks (enums, node attrs, edge attrs, graph schemas)
- 1 error hierarchy task
- 6 graph tasks (FlowGraph class, 3 construction paths, queries, validation)
- 5 analysis tasks (type-compat, build-type-edges, ordering, template-validation, defaults)
- 5 component tasks (Operation, Sequential, Parallel, Conditional, Map)
- 2 host config tasks (GraphologyHostConfig, ReactiveHostConfig)
- 4 reactive tasks (WorkflowRoot, node-status, max-concurrency, retry-semantics)
- 3 review tasks (foundation, reactive-and-hosts, complete-library)
- 5 meta cluster tasks (schema, graph, component, reactive, analysis layers)
- 1 API exports task

Validated with taskgraph: zero cycles, 38 tasks, 12 parallel generations.
Critical path: 12 tasks through reactive execution layer.

Description

Implement the ReactiveHostConfig that renders a ujsx workflow template into a reactive execution engine with signal-backed NodeStatus tracking, computed preconditions, and failure propagation. This is the runtime execution rendering path.

Acceptance Criteria

src/host/reactive.ts exports ReactiveHostConfig implementing ujsx HostConfig<WorkflowTag, WorkflowNode, ReactiveContext>
WorkflowNode: { key, type, status: Signal<NodeStatus>, preconditions: Computed<boolean>, blockedByFailure: Computed<boolean>, operationId?, output?: Signal<unknown>, children: WorkflowNode[] }
ReactiveContext: { operationRegistry, nodes: Map, statusSignals: Map, preconditions: Map, blockedByFailure: Map, resultProjection: EventLogProjection, parentMap, siblingMap, results: Map }
createInstance("operation", props, ctx): creates WorkflowNode with status signal from ReactiveContext, registers in context maps
createInstance for structural containers: creates WorkflowNode tracking children but no graph node
Prerequisite computation: Sequential child → previous sibling completed/skipped; Parallel child → parent's preconditions met; Conditional child → condition evaluates to true
Status propagation: effects on preconditions and blockedByFailure drive state transitions
removeChild: removes parent-child dependency, preconditions/blockedByFailure auto-re-evaluate (reactive)
removeChildFromHost: disposes node's signal references from context maps
Re-exported from src/host/index.ts
Integration tests: render template → assert signal initial states, transition predecessor → assert dependent precondition updates, failure propagation, Conditional as error boundary
