PR Summary

Medium Risk
Changes core DAG construction for snapshot resumes only, but incorrect reachability could affect HITL and other pause/resume flows.

Overview
Fixes HITL snapshot resume when the workflow has a disconnected starter (e.g. a default starter block not wired to the webhook/HITL path). In that case, trigger-only DAG construction could omit downstream resume targets, so persisted remainingEdges could not reach blocks like the post-HITL step.

DAGExecutor.execute() now passes includeAllBlocks: true to DAGBuilder.build() when resumeFromSnapshot is set—the same full enabled-block DAG behavior already used for run-from-block.

A regression test covers webhook → HITL → generate-report with an isolated starter and asserts the resumed DAG includes generate-report with an edge from hitl.

Greptile Summary

This PR fixes snapshot resume DAG construction for HITL workflows. The main changes are:

• Builds the full enabled-block DAG when resuming from a snapshot.
• Preserves downstream resume targets referenced by persisted remainingEdges.
• Adds a regression test for a disconnected starter with a HITL continuation.

Confidence Score: 5/5

This looks safe to merge.

• No blocking issues found in the changed code.
• Snapshot resumes still queue explicit continuation work instead of automatically running every enabled block.
• Disabled blocks remain excluded from the expanded DAG.
