gsxdsm 1cf86baa1c refactor: package code organization wave 18 (executor pure peels) (#3317)
## Summary

Wave 18 continues the package code-organization program after wave 17
domain folders (U4 Slice A from
`docs/plans/2026-07-14-001-refactor-package-code-organization-plan.md`).

### What changed
Peel **pure, behavior-preserving** helpers out of
`packages/engine/src/executor.ts` into domain modules under
`packages/engine/src/executor/`, with **stable re-exports** from
`executor.ts` so deep imports and `vi.mock("../executor.js")` keep
working.

| New module | Symbols |
|------------|---------|
| `executor/task-done-refusal.ts` | `evaluateTaskDoneRefusal`,
`determineRevisionResetStart`, skip-bypass refusal helper |
| `executor/workflow-feedback-paths.ts` |
`extractReferencedPathsFromWorkflowFeedback`,
`isAlwaysAllowedScopeLeakPath`, `workflowPathMatchesDeclaredScope` |
| `executor/workflow-step-verdict.ts` |
`FUSION_WORKFLOW_STEP_CONVENTIONS_PREAMBLE`, `parseWorkflowStepVerdict`
/ `parseWorkflowStepOutput`, step outcome types |
| `executor/await-input-parse.ts` | `parseAwaitInputSentinel`,
`parseAwaitInputQuestionToolCall` |
| `executor/no-commit-eligibility.ts` | `getNoCommitEligibilityReason`
(+ prompt heuristics) |

`executor.ts` live LOC ~**22817 → ~22427** (first pure-peel batch; more
peels needed to approach the 2k cap).

### Shims
- `old path` `executor.ts` public exports → `new path` `executor/*.ts` →
delete-when consumer deep-imports are re-pointed (not this PR)

### Test plan
- [x] `@fusion/engine` typecheck
- [x] Oracle: task-done refusal, skip-bypass, workflow malformed
verdict, scope-leak allowlist, executor-step-session, executor-prompt
- [x] `vitest --project=engine-core` (merge-gate curated suite)
- [ ] CI merge gate

**Stack:** wave17 (merged) → **this PR**

## Summary by CodeRabbit

* **New Features**
* Improved recognition of workflow outcomes from structured and
conversational responses.
* Added support for extracting questions from await-input responses and
tool calls.
* Improved workflow feedback handling for referenced files and declared
scope patterns.
* Added clearer guidance for task execution, approvals, verification,
and available tools.

* **Bug Fixes**
* Prevented completion when required review approvals are missing or
revisions remain pending.
* Improved handling of workflows that legitimately require no code
changes.
  * Added clearer refusal messages and more reliable revision restarts.
  * Sanitized repository paths in Git remediation instructions.

FNXC:CodeOrganization 2026-08-03-07:30:
Wave18 peels evaluateTaskDoneRefusal into executor/task-done-refusal.ts; executor.ts
re-exports it. The single-implementation invariant still holds: one export function
declaration in the domain module, multiple call sites in the executor facade.
FNXC:CodeOrganization 2026-08-03-13:45:
Implicit completion path peels into completion-predicates.ts; count call sites across
facade + that peel so the ratchet still covers explicit and implicit routes.
FNXC:CodeOrganization 2026-08-03-13:10:
Explicit fn_task_done path peels into create-task-done-tool.ts; include that call site
so the ratchet still counts both routes after the U4 tool peel.
