glm-5.1 d2eaa0dd77 feat(schema/graph-schemas): define TaskGraphNodeAttributes, TaskGraphEdgeAttributes, and SerializedGraph generic

Implements graph attribute schemas and the SerializedGraph generic factory
parameterized with <N, E, G> following the graphology JSON format.

- TaskGraphNodeAttributes: name + optional categorical enums (scope, risk,
  impact, level, priority, status) — analysis-relevant metadata only
- TaskGraphNodeAttributesUpdate: Type.Partial(TaskGraphNodeAttributes)
- TaskGraphEdgeAttributes: optional qualityRetention number
- SerializedGraph<N, E, G>: generic factory for graphology JSON format
- TaskGraphSerialized: concrete instantiation with empty graph attributes
- No schema version field per spec

35 new tests covering validation, rejection, and compile-time type safety.

Description

Define graph attribute schemas and the serialized graph generic in src/schema/graph.ts. TaskGraphNodeAttributes carries only analysis-relevant metadata (no tags, assignee, due, etc.). SerializedGraph is a generic factory parameterized with node and edge attribute types.

Acceptance Criteria

src/schema/graph.ts exports:
- TaskGraphNodeAttributes schema: name: Type.String(), optional categorical enums (scope, risk, impact, level, priority, status) — not nullable on the graph (absent = not stored)
- type TaskGraphNodeAttributes derived
- TaskGraphNodeAttributesUpdate = Type.Partial(TaskGraphNodeAttributes) and type alias
- TaskGraphEdgeAttributes schema: qualityRetention: Type.Optional(Type.Number())
- type TaskGraphEdgeAttributes derived
- SerializedGraph generic factory parameterized with <N extends TSchema, E extends TSchema, G extends TSchema>
- TaskGraphSerialized = SerializedGraph(TaskGraphNodeAttributes, TaskGraphEdgeAttributes, Type.Object({})) and type alias
SerializedGraph generic follows graphology JSON format: attributes, options: { type: "directed", multi: false, allowSelfLoops: false }, nodes: [{ key, attributes }], edges: [{ key, source, target, attributes }]
No schema version field on TaskGraphSerialized per spec
Re-exported from src/schema/index.ts

References

docs/architecture/schemas.md — graph attribute schemas, SerializedGraph
docs/research/typebox-patterns.md — section 6 (generic schema factories)

Notes

Follows the architecture spec in docs/architecture/schemas.md and the generic schema factory pattern from docs/research/typebox-patterns.md section 6. The SerializedGraph generic factory uses the recommended graphology JSON format with Type.Literal("directed"), Type.Literal(false), and Type.Literal(false) for the options. No default on qualityRetention in the graph schema (unlike DependencyEdge which has Type.Number({ default: 0.9 })) — the graph schema keeps it simple with Type.Optional(Type.Number()).

Summary

Implemented graph attribute schemas and serialized graph generic factory per spec.

Created: src/schema/graph.ts (TaskGraphNodeAttributes, TaskGraphNodeAttributesUpdate, TaskGraphEdgeAttributes, SerializedGraph generic, TaskGraphSerialized, and all type aliases)
Modified: test/schema.test.ts (35 new tests for graph schemas: TaskGraphNodeAttributes, TaskGraphNodeAttributesUpdate, TaskGraphEdgeAttributes, SerializedGraph, and compile-time type verification)
Tests: 121 total, all passing; tsc --noEmit clean
