feat(graph/queries): implement query methods — hasCycles, findCycles, topologicalOrder, dependencies, dependents, taskCount, getTask
...
- hasCycles(): uses graphology-dag.hasCycle() as fast boolean check
- findCycles(): SCC pre-check + custom 3-color DFS for cycle path extraction
- topologicalOrder(): graphology-dag.topologicalSort + CircularDependencyError on cycle
- dependencies/dependents: inNeighbors/outNeighbors with TaskNotFoundError
- taskCount(): graph.order, getTask(): node attributes or undefined
- 45 unit tests covering all acceptance criteria

feat(graph/construction): implement TaskGraph construction methods
...
- fromTasks: bulk import via serialized blob, orphan nodes for dangling refs,
DuplicateNodeError for duplicates, edge dedup, null→undefined stripping
- fromRecords: strict validation (TaskNotFoundError for dangling refs,
DuplicateEdgeError for duplicate edges), per-edge qualityRetention
- fromJSON: TypeBox Value.Check validation, InvalidInputError on schema failure,
orphan nodes preserved
- addTask: throws DuplicateNodeError if ID exists
- addDependency: throws TaskNotFoundError/DuplicateEdgeError, deterministic
edge keys per ADR-006, default qualityRetention 0.9
- taskInputToNodeAttrs: strips null→undefined for categorical fields,
drops non-graph fields (tags, assignee, due, created, modified)
- 47 new unit tests (304 total, all passing)

feat(cost-benefit): implement calculateTaskEv pure function
...
Implement the core EV calculation: EV = p*C_success + (1-p)*C_fail
where C_success = scopeCost*impactWeight, C_fail = scopeCost*impactWeight + fallbackCost + timeLost*expectedRetries.
- expectedRetries = (1-p)/p when p>0, else 0 (geometric series)
- Caps expectedRetries at config.retries when retries > 0
- Multiplies final EV by config.valueRate when non-zero
- 30 unit tests covering formula, edge cases, and Python research model values

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.

categorical fields as Optional(Nullable(...)), metadata fields)
- Add DependencyEdge schema with from, to, qualityRetention fields
- Re-export Nullable helper from task.ts for convenience
- Add type aliases: TaskInput, DependencyEdge via Static<typeof>
- Add 49 tests covering validation, nullable fields, edge cases, type correctness
