refactor(workflow): cleanup engine re-exports, final verification (Phase 4)

- Remove all re-exports from @uncaged/workflow -> @uncaged/workflow-runtime
- Fix cli-workflow imports to use @uncaged/workflow-runtime for types
- Update bundle-validator to allow @uncaged/workflow-runtime imports
- Update init templates to reference @uncaged/workflow-runtime
- 378 tests passing, build + check clean

 Workflow bundles (`.esm.js`) follow the same rule: export `const run` and `const descriptor`, not `export default`.
 
+### Folder Module Discipline
+
+Every folder under `src/` is a **module boundary**. Four rules:
+
+| # | Rule | Rationale |
+|---|------|-----------|
+| 1 | **Every folder exports via `index.ts`** | Single entry point for the module |
+| 2 | **Types live in `types.ts`** | Each folder's type definitions go in `<folder>/types.ts`, not scattered across files |
+| 3 | **Single export source** | Only `index.ts` may re-export. No file may re-export from another module's internals. Cross-module imports must go through `index.ts` — never reach past it to import a specific file |
+| 4 | **`index.ts` is pure re-exports** | No type definitions, no function implementations — only `export { ... } from` statements |
+
+```typescript
+// ✅ Good — import through module boundary
+import { createCasStore } from "../cas/index.js";
+import type { CasStore } from "../cas/index.js";
+
+// ❌ Bad — reaching past index.ts
+import { createCasStore } from "../cas/cas.js";
+
+// ❌ Bad — re-exporting from non-index file
+// in engine/engine.ts:
+export { createCasStore } from "../cas/cas.js";
+
+// ❌ Bad — types defined in index.ts
+// in cas/index.ts:
+export type CasStore = { ... };  // should be in cas/types.ts
+```
+
+**Exception**: The package-level `src/index.ts` is the public API surface and re-exports from folder `index.ts` files. Files that remain at `src/` root (e.g. `types.ts`, `workflow-as-agent.ts`) are not inside a folder module and follow normal rules.

+# @uncaged/cli-workflow
+
+Command-line interface for the Uncaged workflow engine (`uncaged-workflow`).
+
+The CLI reads and writes the workflow registry, starts and inspects threads, manages CAS blobs, and prints agent-oriented reference docs via `skill`. It uses the same storage layout as `@uncaged/workflow` (default `~/.uncaged/workflow`).
+
+## Install
+
+```bash
+bun add @uncaged/cli-workflow
+```
+
+In this monorepo: `"@uncaged/cli-workflow": "workspace:*"`. Depends on `"@uncaged/workflow": "workspace:*"`.
+
+## Usage
+
+```bash
+uncaged-workflow workflow list
+uncaged-workflow run <name> --prompt "Your task"
+uncaged-workflow thread show <id>
+uncaged-workflow skill
+```
+
+Invoking the CLI with no command (or from this repo: `bun packages/cli-workflow/src/cli.ts`) prints:
+
+```
+uncaged-workflow — workflow engine CLI
+
+Workflow registry:
+  workflow add <name> <file.esm.js> [--types <path>]  Register a workflow bundle in the registry

+`AgentFn` adapter that runs the `cursor-agent` CLI against a workspace path derived from the thread.
+
+The agent builds a full prompt (system + task + step history via `@uncaged/workflow-util-agent`), extracts the absolute workspace path with your `extract` + Zod schema, then spawns `cursor-agent` with `--workspace`, model, and non-interactive flags.
+
+## Install
+
+```bash
+bun add @uncaged/workflow-agent-cursor @uncaged/workflow @uncaged/workflow-util-agent zod
+```
+
+In this monorepo: `"@uncaged/workflow-agent-cursor": "workspace:*"` plus `workspace:*` for `@uncaged/workflow` and `@uncaged/workflow-util-agent`.
+
+## Usage
+
+```typescript
+import { createCursorAgent } from "@uncaged/workflow-agent-cursor";
+
+const agent = createCursorAgent({
+  model: null, // null → "auto"
+  timeout: 0, // ms; 0 = no limit (spawnCli timeout disabled)
+  extract: myExtractFn,
+});
+```
+
+## API overview
+
+| Export | Description |
+|--------|-------------|
+| `createCursorAgent(config)` | Returns `AgentFn` that runs `cursor-agent` with `buildAgentPrompt(ctx)` |
+| `CursorAgentConfig` | `model`, `timeout`, `extract` (must supply workspace path) |
+| `validateCursorAgentConfig` | Config validation result |
+| `buildAgentPrompt` | Re-exported from `@uncaged/workflow-util-agent` |
+
+Requires `cursor-agent` on `PATH` at runtime.

+`AgentFn` adapter that runs the `hermes` CLI in non-interactive `chat` mode (Nerve-style flags: `-q`, `--yolo`, `--quiet`, bounded `--max-turns`).
+
+The agent composes the same thread-aware prompt as other CLI-backed agents via `buildAgentPrompt` from `@uncaged/workflow-util-agent`, then spawns `hermes` and returns stdout on success.
+
+## Install
+
+```bash

+
+In this monorepo: use `workspace:*` for all three `@uncaged/*` packages.

+```typescript
+import { createHermesAgent } from "@uncaged/workflow-agent-hermes";
+
+const agent = createHermesAgent({
+  model: "your-model", // or null to omit --model
+  timeout: 600_000, // ms, or null for no timeout
+});

+# @uncaged/workflow-template-develop
+
+Reference **develop** workflow template: plan phases, implement in a loop, review, test, then commit.
+
+Export a `WorkflowDefinition` and `createDevelopRun` so a host can bind agents/LLM and run the same graph the bundled `.esm.js` would use. Use `buildDevelopDescriptor()` when assembling `descriptor` metadata for a bundle.
+
+## Install
+
+```bash
+bun add @uncaged/workflow-template-develop @uncaged/workflow zod
+```
+
+In this monorepo: `workspace:*` for `@uncaged/workflow-template-develop` and `@uncaged/workflow`.
+
+## Usage
+
+```typescript
+import { createDevelopRun, developWorkflowDefinition } from "@uncaged/workflow-template-develop";
+
+const run = createDevelopRun(binding, extract, llmProvider);
+// run(...) executes the develop moderator graph with your AgentBinding
+```
+
+## Roles
+
+| Role | Purpose |
+|------|---------|
+| **planner** | Break work into ordered phases (hashes) |
+| **coder** | Implement current phase; repeats until phases complete or limits hit |
+| **reviewer** | Code review gate (`approved` vs send back to coder) |
+| **tester** | Verify via tests/build/lint (`passed` vs send back to coder) |
+| **committer** | Final commit step |
+
+Also exported: role factories/meta schemas (`plannerRole`, `coderRole`, …), `DevelopMeta`, `developRoles`.
+
+## Moderator flow
+
+1. **Start** → `planner`  
+2. After **planner** → `coder`  
+3. After **coder** → if all planned phases are done (or last phase completed) → `reviewer`; else `coder` again, until `maxRounds` then `END`  
+4. After **reviewer** → if approved → `tester`; else `coder` (or `END` if out of rounds)  
+5. After **tester** → if passed → `committer`; else `coder` (or `END` if out of rounds)  
+6. After **committer** → `END`
+
+## API overview
+
+| Export | Description |
+|--------|-------------|
+| `createDevelopRun` | `createWorkflow(developWorkflowDefinition, …)` factory |
+| `developWorkflowDefinition` | `description`, `roles`, `developModerator` |
+| `developModerator` | `Moderator<DevelopMeta>` |

+# @uncaged/workflow-template-solve-issue
+
+Reference **solve-issue** workflow template: prepare a repo, delegate implementation to the **develop** workflow, then submit (e.g. open a PR).
+
+`createSolveIssueRun` wires the `developer` role to `workflowAsAgent("develop")` by default; `binding.overrides.developer` wins if you pass one (for tests or custom hosts).
+
+## Install
+
+```bash
+bun add @uncaged/workflow-template-solve-issue @uncaged/workflow zod
+```
+
+In this monorepo: `workspace:*` for this package and `@uncaged/workflow`.

+
+```typescript
+import { createSolveIssueRun, solveIssueWorkflowDefinition } from "@uncaged/workflow-template-solve-issue";
+
+const run = createSolveIssueRun(binding, extract, llmProvider);
+```
+
+## Roles
+
+| Role | Purpose |
+|------|---------|
+| **preparer** | Set up context / repo state for the issue |
+| **developer** | Implementation; default runs the registered `develop` workflow as a sub-agent |
+| **submitter** | Finalize and submit the outcome (e.g. PR) |
+
+Also exported: `preparerRole`, `developerRole`, `submitterRole` and their Zod meta schemas, `SolveIssueMeta`, `solveIssueRoles`.
+
+## Moderator flow
