Fix ERR_MODULE_NOT_FOUND by codegen sdkProtocolVersion.ts

[Copilot]

Versions 0.1.10+ fail at runtime with ERR_MODULE_NOT_FOUND because the built dist/sdkProtocolVersion.js imports ../../sdk-protocol-version.json, which is excluded from the published package.

Changes

• Extended scripts/update-protocol-version.ts to generate TypeScript code (already generates Go/Python/C#)
• Generated src/sdkProtocolVersion.ts with protocol version as a hardcoded constant
• Fixed npm script name from generate-protocol-version.ts → update-protocol-version.ts

Before

import sdkProtocolVersion from "../../sdk-protocol-version.json";

export function getSdkProtocolVersion(): number {
    return sdkProtocolVersion.version;
}

After

export const SDK_PROTOCOL_VERSION = 1;

export function getSdkProtocolVersion(): number {
    return SDK_PROTOCOL_VERSION;
}

Built output now contains no external imports, consistent with other SDK languages.

<issue_title>Missing Module Error in SDK Versions 0.1.10 and 0.1.11</issue_title>
<issue_description>## Summary
@github/copilot-sdk versions 0.1.10 and 0.1.11 fail at runtime with ERR_MODULE_NOT_FOUND due to an incorrect import statement in dist/sdkProtocolVersion.js. Version 0.1.9 works correctly.

Environment

• Node.js: v22.21.1
• Platform: GitHub Actions (ubuntu-latest)
• Module Type: ESM ("type": "module")

Error Message

Error [ERR_MODULE_NOT_FOUND]: Cannot find module '@github/sdk-protocol-version.json' 
imported from /home/runner/work/.../node_modules/@github/copilot-sdk/dist/sdkProtocolVersion.js

Affected Versions

Version	Status
0.1.9	✅ Works
0.1.10	❌ Broken
0.1.11	❌ Broken

Reproduction Steps

1. Create a new Node.js project with "type": "module"
2. Install @github/copilot-sdk@0.1.11 (or 0.1.10)
3. Import any module from the SDK
4. Run with Node.js 22.x

Workaround

Pin to version 0.1.9:

"@github/copilot-sdk": "0.1.9"

Pull request overview

This pull request fixes a critical module resolution error in SDK versions 0.1.10 and 0.1.11 where the TypeScript SDK was attempting to import sdk-protocol-version.json, but the JSON file was not included in the npm package distribution. The fix generates a TypeScript file with hardcoded protocol version constants instead of importing from JSON, consistent with how Go, Python, and .NET SDKs already handle protocol versioning.

Changes:

• Updated update-protocol-version.ts script to generate TypeScript code with hardcoded version constant
• Modified nodejs/src/sdkProtocolVersion.ts to export a constant instead of importing JSON
• Fixed npm script name from generate-protocol-version to update-protocol-version
• Updated comments across all language implementations to reference the correct script name
