Move docs/ package mirror into document-navigator plugin

Relocate the ~6k-file docs tree from the repo root into
plugins/document-navigator/docs/ so the plugin is self-contained and
portable. docs/superpowers/ (specs and plans) stays at the repo root.

Moved via cp+rm rather than git mv because directory rename() fails with
EPERM on this WSL /mnt DrvFs mount; git rename-detection pairs the
identical-content files at commit time.

+# create-suaveplan-plugin
+
+Interactive scaffold for new Suaveplan API plugins. Generates a complete,
+immediately-testable plugin skeleton — `plugin.json`, `definePlugin`
+body, host test, optional integration test wired to the matching
+`testing-integration-{postgres,sqlite,surrealdb}` fixture, both vitest
+configs, migrations, and a README — tailored to the selected isolation
+tier, capability set, and DB engine.

+
+## Quick start
+
+```bash
+bunx create-suaveplan-plugin my-plugin --fixture trusted-postgres-full
+cd my-plugin
+bun test
+```
+
+Three fixtures cover the canonical permutations:
+
+| Fixture | Isolation | Database | Capabilities |
+| --- | --- | --- | --- |
+| `trusted-postgres-full` | `trusted` | `postgres` | rest, graphql, ws, sse, sagas, twoPhaseCommit, perTenantJobs |
+| `isolated-sqlite-rest-only` | `isolated` | `sqlite` | rest |
+| `sandboxed-none-rest-only` | `sandboxed` | `none` | rest |
+
+## CLI flags
+
+- `<name>` — positional plugin name (validated against npm rules).
+- `--fixture <id>` — one of the three fixtures above (default
+  `sandboxed-none-rest-only`).
+- `--dir <path>` — explicit target directory (default `<cwd>/<name>`).
+- `--force` — overwrite an existing non-empty target.
+
+## Programmatic API
+
+```ts
+import { scaffold, answersForFixture } from "create-suaveplan-plugin";
+
+scaffold({
+    answers: answersForFixture("isolated-sqlite-rest-only", "billing-plugin"),
+    targetDir: "./billing-plugin",
+    force: false,
+});
+```
+
+## Error codes
+
+The scaffold raises only typed `ScaffoldError`s. Every code is namespaced
+as `SCAFFOLD.*`:
+
+- `SCAFFOLD.INVALID_NAME` — name violates npm-package-name rules.
+- `SCAFFOLD.DIRECTORY_EXISTS` — target is non-empty and `--force` was not given.
+- `SCAFFOLD.WRITE_FAILED` — fs write failed; original error attached via `cause`.
+- `SCAFFOLD.UNKNOWN_ENGINE` — engine outside the closed vocabulary.
+
+## Verification
+
+The package ships three verification surfaces:
+
+1. **Unit tests** — every render branch, every prompt validation case.
+2. **Snapshot tests** — byte-for-byte against the committed
+   `tests/scaffold-output/snapshots/<fixture>/**` trees.
+3. **Scaffold-and-run** — for each fixture, scaffold to a temp dir and
+   run `bun test` against it. Exit code must be 0.
+
+Run the full gate via:
+
+```bash
+bunx --bun turbo lint typecheck test:coverage --filter=create-suaveplan-plugin
+```
