fix(ci): bump smoke-test MCP v2 pin to 2.0.0-beta.4

[chelojimenez]

What

The Smoke packed npm packages CI job hardcodes an exact expected version for the MCP v2 packages:

// .github/scripts/smoke-packed-npm-packages.mjs
const expectedMcpV2PackageVersion = "2.0.0-alpha.2";

readExpectedMcpV2Versions() throws if any publishable package's pin for @modelcontextprotocol/{client,node,server} isn't exactly that string. The SDK/CLI/inspector deps were since bumped to 2.0.0-beta.4, so the assertion fires on the first spec it reads:

Error: @mcpjam/sdk must pin @modelcontextprotocol/client to 2.0.0-alpha.2, got "2.0.0-beta.4".

Fix

Bump the constant to 2.0.0-beta.4 to match the actual pins. Verified all three packages (client/node/server) across sdk, cli, and mcpjam-inspector resolve uniformly to 2.0.0-beta.4.

Note

This guard is deliberately strict (exact pin, lockstep across all packages), so every MCP v2 bump must also touch this constant. If bumps stay frequent, worth deriving the expected version from the SDK's package.json instead of hardcoding — left out of this fix to keep it minimal.

Note

Low Risk
Single constant change in a CI smoke script; no runtime or production code paths affected.

Overview
Updates the Smoke packed npm packages CI script so its hardcoded MCP v2 version matches the repo’s exact pins on @modelcontextprotocol/client, node, and server.

expectedMcpV2PackageVersion moves from 2.0.0-alpha.2 to 2.0.0-beta.4, aligning with sdk, cli, and mcpjam-inspector and stopping readExpectedMcpV2Versions() from failing when it compares workspace package.json specs to the stale constant.
