apps/libs/sdk-typescript was deleted in #738 (merged into #735 in this
branch). The Dockerfile.source COPY line was kept by mistake and broke
the Deploy API image build:

The remaining 4 libs (runner-api-client, api-client, analytics-api-client,
toolbox-api-client) are what the API actually imports at runtime.

Reverts #743. Restores `apps/libs/sdk-typescript` and the dashboard
cloudBox usage to the pre-#743 state (clean `git revert` of ad155d9, no
manual edits).

## Summary by CodeRabbit

* **New Features**
* Added TypeScript code snippet support to the Playground alongside
existing Python support.
* Introduced the BoxLite TypeScript SDK (`@boxlite-ai/sdk`), a new
package providing APIs for box management, file operations, git
workflows, code execution, and desktop automation.

* **Refactor**
* Migrated internal dashboard box operations to use the new SDK client
library.

…o main) (boxlite-ai#743)

## Summary
- Re-applies boxlite-ai#738 onto `main`. boxlite-ai#738 was merged with base
`feat/box-curated-image-boot` by mistake, so its content never reached
`main`.
- Removes the publishable `apps/libs/sdk-typescript` project and its
Nx/build references.
- Replaces Dashboard's `@boxlite-ai/sdk` usage with the
Dashboard-private `cloudBox` adapter backed by generated REST clients.
- Removes TypeScript Cloud SDK playground snippets so the UI no longer
teaches users to install `@boxlite-ai/sdk`.

## Differences from boxlite-ai#738
Cherry-pick of squash commit `2f5aac6b` with three conflict resolutions
against current `main`:
- `PlaygroundProvider.tsx`: kept the `cloudBox` import side;
`Image.debianSlim('3.13')` → `{ image: 'base' }` (identical to the boxlite-ai#738
resolved tree).
- `apps/dashboard/.storybook/main.ts`: removed a stale `@boxlite-ai/sdk`
vite alias added on `main` after boxlite-ai#738 branched.


## Architecture Context: why delete + rewrite (not a rename)

**What each layer is.** `api-client` is machine-generated from the API's
OpenAPI
spec — it only knows how to call endpoints. The deleted SDK (B) and the
new
`cloudBox.ts` are the *handwritten glue* above it: form-params → DTO
mapping,
poll-until-started, attaching `.process`/`.fs` helpers to box objects.
Glue
logic is not in the OpenAPI contract, so it cannot be generated.

**Why `cloudBox.ts` is `added`, not `renamed`.** It is a from-scratch
minimal
reimplementation of the <5% of the SDK the Dashboard actually used: 458
lines
vs the SDK's 9.8k, only ~9 identical lines with the old `Box.ts`
(`git diff -M20%` detects no rename). Marking it a rename would wrongly
suggest
the full SDK class hierarchy survived.

**Why delete the SDK at all.**
1. *Provenance*: it is Daytona-derived AGPL code in a repo that competes
with
   Daytona — licensing and optics liability.
2. *Maintenance*: every API change (renames, DTO removals, client regen)
had to
   sweep 9.8k lines to serve a single internal consumer using <5% of it.
3. *Strategy*: our public SDK story is the dual-mode native SDKs
(Python/Node/Go/C, embedded engine + optional REST). A parallel
cloud-only
   TS SDK was a competing second "official way".

**What external users keep.** The cloud REST API is unchanged; the
generated
clients (`@boxlite-ai/api-client`, `api-client-go`) remain published.
Only the
convenience wrapper is gone.

**Known follow-ups (out of scope here).**
- `cloudBox.ts` still carries the Daytona AGPL header — needs a
clean-room pass.
- Dead tail to remove once Playground is officially retired: hidden
Playground
routes, `toolbox-api-client` TS package (zero runtime callers), and the
  computer-use/git sections of `cloudBox.ts`.

## Verification
- `vite build --minify false` error set diffed against an `origin/main`
baseline worktree: no new errors beyond pre-existing `main` failures
(line-number shifts only).
- Note: `dashboard:build` is currently broken on `main` itself
(lightningcss minify + `@boxlite-ai/api-client` resolution), unrelated
to this change.

## Relation to boxlite-ai#735
`feat/box-curated-image-boot` (boxlite-ai#735) will be rebuilt on top of this
branch so its diff contains only the curated-image work.

## Summary by CodeRabbit

* **New Features**
* Dashboard now uses the CloudBox-backed API client for box creation and
session flows.

* **Bug Fixes**
* Refactored creation/loading flows to improve reliability when creating
or loading boxes.

* **Removed Features**
* TypeScript code snippet generation removed — Python is now the sole
generated language.
<!-- end of auto-generated comment: release notes by coderabbit.ai -->

- Remove the publishable apps/libs/sdk-typescript project and its
Nx/build references.
- Replace Dashboard's prior @boxlite-ai/sdk usage with a
Dashboard-private cloudBox adapter backed by generated REST clients.
- Remove TypeScript Cloud SDK playground snippets so the UI no longer
teaches users to install @boxlite-ai/sdk.

The large diff is not because the delete itself is complicated. It is
because `apps/libs/sdk-typescript` had two roles mixed together: it was
a customer-facing package, and Dashboard was also importing it as an
internal cloud box facade.

Legend:
- `*** DELETE TARGET ***` = the package this PR removes.
- `*** REMOVED USER SURFACE ***` = user-facing code/docs path removed
because it advertised that package.
- `[kept]` = still exists after this PR.
- `[new internal]` = Dashboard-only replacement, not a public SDK.

Build graph cleanup after deleting the target:
No @boxlite-ai/sdk alias -> no SDK Vite polyfills -> no Nx build edge -> no Docker COPY -> no SDK lint exception
```

So the diff fans out into four necessary buckets:

1. Delete the public SDK project itself: `apps/libs/sdk-typescript/**`.
2. Keep Dashboard working by replacing SDK imports with
`apps/dashboard/src/lib/cloudBox.ts`.
3. Stop advertising the removed SDK in Playground code snippets.
4. Remove build-system references that would otherwise point at a
deleted project.
