Bring two new tutorials — Navigation and Routing, OData V4 — into the
monorepo, and rework all four tutorials onto a single template so they
share the same toolchain, layout, namespace, and documentation
conventions.

Tutorials

- packages/navigation/ — 17 steps imported from the OpenUI5 demokit,
  promoted to the standard `steps/` layout, package names changed to
  `ui5.tutorial.navigation.stepNN`, ui5.yaml metadata aligned with the
  rest of the repo, dev dependencies switched to the walkthrough set
  (@types/openui5, ui5-middleware-serveframework, ui5-tooling-transpile),
  app namespace renamed `sap.ui.demo.nav` -> `ui5.tutorial.navigation`
  across manifests, TS imports, JSDoc, XML controllerName, tsconfig
  paths, and HTML resource-roots.

- packages/odatav4/ — 11 steps imported from the same demokit source,
  restructured from `solutions/` -> `steps/`, root-level markdown moved
  into per-step README.md, shared `images/` split into per-step
  `assets/`. JS sources fully converted to TypeScript ES modules
  (Component, App.controller, model/models, initMockServer, the ~800-
  line sinon-based mock server, view XML), Hungarian variable prefixes
  stripped (oModel -> model, aMatches -> matches, sUrl -> url, ...) to
  match the project's TS style. App namespace standardised to
  `ui5.tutorial.odatav4`.

Namespace alignment across the existing tutorials

- packages/walkthrough/ renamed `ui5.walkthrough` -> `ui5.tutorial.walkthrough`
  across ~630 files (manifests, TS imports + @namespace, XML
  controllerName + xmlns, tsconfig paths, HTML resource-roots, every
  README code snippet, step package.json names).
- packages/quickstart/ renamed `ui5.quickstart` -> `ui5.tutorial.quickstart`
  with the same shape across 27 files; ui5.yaml `metadata.name`
  `quickstart-tutorial` -> `ui5.tutorial.quickstart`.

After this commit, all 69 step workspaces follow the same naming
convention: `ui5.tutorial.<tutorial>.stepNN`.

Documentation

- Per-tutorial overview READMEs (packages/{navigation,odatav4}/README.md)
  now mirror packages/walkthrough/README.md: each step bullet has an
  inline `[🔗 Live Preview]` link and paired `<details class="ts-only">` /
  `<details class="js-only">` `[📥 Download Solution]` blocks.
- Step READMEs ship with paired ```ts / ```js code blocks so the
  Jekyll code-couple toggle renders both flavours. JS half generated
  from the build's sanitized `*-dbg.js` output where applicable.
- Folder-structure images replaced with fenced ```text ASCII trees
  (using `.?s` placeholders so the global toggle flips the extensions);
  images deleted from the per-step assets.
- All callout syntaxes (GitHub-flavoured alerts `> [!NOTE]` plus
  walkthrough's emoji blockquotes `> 📝 **Note:** <br>`) normalised to
  the `:note:` / `:tip:` / `:info:` / `:caution:` / `:warning:`
  shorthand mandated by `_/AUTOMATE.md`.
- Step-level "view and download all files at \[demokit\]" links
  retargeted to the published `https://ui5.github.io/tutorials/...`
  URLs so they resolve against the local dist via the dev server.
- License year bumped 2025 -> 2026 across all overview READMEs;
  `## License` sections added to the navigation and odatav4 overviews
  to match the walkthrough/quickstart convention.

Tooling

- tools/dev-server/server.js: mount `dist/` under `/dist/...` so
  `npm start` serves the locally-built apps and ZIPs; rewrite the
  published `https://ui5.github.io/tutorials/...` URLs in rendered
  markdown to the local `/dist/...` paths for the four known tutorial
  slugs (walkthrough, quickstart, navigation, odatav4); friendly hint
  page when an artifact is missing.
- README.md: document the `npm install && npm run build && npm start`
  workflow.

Verification

- `npm install` succeeds and registers all 69 workspaces under the new
  `ui5.tutorial.*` namespace.
- `npm run typecheck -ws --if-present` exits 0.
- `npm run build` exits 0; produces `dist/<tutorial>/build/NN/` apps,
  `<tutorial>-step-NN.zip` and `<tutorial>-step-NN-js.zip` downloads,
  and the rewritten `dist/index.md` overview for each tutorial.
- `index-cdn.html` present for every webapp that bootstraps SAPUI5
  (68 of 69 — walkthrough step 01 is the bare HTML "Hello World" and
  intentionally has none).
- Dev-server smoke test: Live Preview links from the overview README
  resolve to `/dist/<tutorial>/build/NN/index-cdn.html` with HTTP 200.

Versions
- Bump framework to OpenUI5 1.148.1 (latest LTS patch) in every step
  ui5.yaml and CDN bootstrap URL.
- Bump manifest _version to 2.8.0 and minUI5Version to 1.148 across
  all 69 manifests (mapping per UI5/manifest v2/mapping.json).
- specVersion: "4.0" for every ui5.yaml.
- @types/openui5 ^1.148.0 in every step package.json.
- Sync README narrative and inline manifest snippets that referenced
  OpenUI5 1.120 / _version 1.60.0 / 1.38.0 to the new values.

Reviewer findings (PR #295, @flovogt)
- Manifest v2 (_version 2.8.0).
- specVersion '4.0'.
- Ensure trailing newline on every webapp source file.

Cross-tutorial inconsistency cleanup
- Quickstart Component.ts: @namespace sap.m.tutorial.quickstart.NN
  -> ui5.tutorial.quickstart, switch to public static metadata and
  add interfaces: ["sap.ui.core.IAsyncContentCreation"].
- Strip residual Hungarian-notation in quickstart controllers/index.ts
  (oEvent/bState/oView) and the named identifiers in odatav4 OPA tests
  (iGrowingBy/sViewName/oListBinding).
- Add explicit "strict": false, "strictNullChecks": false to walkthrough
  and quickstart tsconfig.json files (match navigation/odatav4).
- Drop redundant data-sap-ui-libs from quickstart steps 02 and 03
  index.html (Component manifest already declares the libs).
- Add data-sap-ui-theme="sap_horizon" to quickstart and navigation
  bootstrap script tags so the theme is explicit and consistent with
  walkthrough/odatav4.

Indentation normalization per .editorconfig
- JSON / XML / YAML / .properties -> 2 spaces.
- TS / JS / HTML -> tabs.
- Re-indent fenced code blocks inside step README.md files to match
  the same conventions so doc snippets mirror the actual source files.

Verified: npm run typecheck and npm run build both exit 0; ui5-linter
clean on sampled steps; manifest validation clean.

Replace deprecated @types/openui5 package with the official @openui5/types
package across all tutorial packages and steps. Updates include:

- package.json: @types/openui5 → @openui5/types in devDependencies
- tsconfig.json: Updated types array entries
- README.md: Updated documentation references

This aligns with the OpenUI5 project's official type definitions package.
