Generalizes the foreach-only bounded-rework mechanism to the top-level
graph walk so the PR review loop (await-review -> pr-respond -> rework
back) is a legal bounded cycle: a kind:rework back-edge to a stacked node
returns a ReworkSignal the loop-head re-runs up to maxReworkCycles, then
routes outcome:rework-exhausted. Non-rework cycles still throw 'Cycle
detected' (safety preserved); foreach rework unchanged (shared core
constants). Adds createAutoMergeGateHandler (live entity re-fetch +
isPrEntityAutoMergeReady -> auto-on/auto-off). Pins R14: graph-executed
PR tasks merge through pr-merge, never the legacy queue. 122 graph tests
green.

Adds the three first-class PR workflow node kinds and their handlers via
createPrNodeHandlers(deps), registered in createDefaultNodeHandlers
(fail-closed pr-nodes-unwired when absent). GitHub ops are injected as
callbacks (PrNodeGithubOps) at all three CLI sites (daemon/serve/dashboard)
so the engine never imports the dashboard client (FN-3049). pr-create
routes open/failed as outcomes; pr-merge passes expectedHeadOid and never
writes 'merged' (reconcile corroborates); pr-respond delegates to an
injected respond callback (U5 fills the body). 10 tests.

Prompt nodes now support an executor kind: model (provider/model override),
agent (adopts a named agent's model + custom instructions), skill (prompt
becomes a skill invocation), and cli (named project script with the prompt in
FUSION_NODE_PROMPT — raw commands still never accepted). Per-node maxRetries
overrides the executor-wide default (capped at 10). Await-input nodes pause the
task with status 'awaiting-user-input' and the question as pausedReason; on
unpause the newest steering comment is consumed as the answer and exposed in
graph context.
Non-seam prompt/script nodes now dispatch to an injected WorkflowCustomNodeRunner
instead of throwing; gate nodes support an executable (prompt/script-backed) form
alongside the original context-gate contract. WorkflowGraphExecutor accepts the
runner via deps.
Add the Phase 2 workflow-graph interpreter scaffold and builtin coding IR wiring while keeping execution behavior unchanged by default.
- add BUILTIN_CODING_WORKFLOW_IR and builder in @fusion/core with coverage tests
- export new coding workflow IR APIs from core index
- add WorkflowGraphExecutor scaffold in @fusion/engine plus parity-focused test coverage
- document the flagged-off interpreter scaffold, parity gate, and v1 IR gap reconciliation in workflow docs
- include a changeset for published @runfusion/fusion
