  2. fix(anthropic): handle encrypted_code_execution_result for multi-turn… 

    … with web_fetch/web_search 20260209 (#13046)

## Problem

When using `web_fetch_20260209` or `web_search_20260209`, the Anthropic
API auto-injects a `code_execution` `server_tool_use` block in the
response and returns its result as an `encrypted_code_execution_result`.
The SDK previously only handled `code_execution_result` and
`code_execution_tool_result_error` types, so the encrypted result was
**silently dropped**.

In multi-turn conversations, the absence of this
`code_execution_tool_result` in the subsequent user message caused the
Anthropic API to return:

```
messages.1: `code_execution` tool use with id `srvtoolu_01HopAaXMHo9To3RavUYwqy7` was found without a corresponding `code_execution_tool_result` block
```

Repro: use the example pages in `examples/ai-e2e-next`:
- `/chat/anthropic-web-fetch-20260209`
- `/chat/anthropic-web-search-20260209`

Then send a follow-up message after a tool call was made in the previous
response.

Fixes #13040

## Fix

- **`anthropic-messages-language-model.ts`** (both streaming and
non-streaming paths): when `code_execution_tool_result.content.type ===
'encrypted_code_execution_result'`, emit a `tool-result` event carrying
the encrypted payload so it is preserved in the conversation history
- **`convert-to-anthropic-messages-prompt.ts`**: when reconstructing the
user message for multi-turn, detect `encrypted_code_execution_result`
output and emit the correct `code_execution_tool_result` block with the
encrypted content (checked before the existing `code_execution_result`
branch)
- **`convert-to-anthropic-messages-prompt.test.ts`**: add a test
covering the encrypted result round-trip in a multi-turn context
