Update build command for MCP in README

Closes #1599

[Copilot]

Pull request overview

Updates the root README’s MCP build instructions to reference an existing npm script, addressing issue #1599 where the documented command fails due to a missing build:mcp-bundle script.

Changes:

• Replaces npm run build:mcp-bundle with npm run build:mcp in the “Run locally” instructions.

This section now instructs running npm run build:mcp, but the README still references the non-existent build:mcp-bundle script in later MCP sections (e.g., “Bundle MCP into CLI” / “Test the MCP server locally”). Please update those remaining occurrences (or reintroduce a build:mcp-bundle script) so the documentation is consistent and users don’t hit the same missing-script error elsewhere.

Updated in commit e54eedf. All remaining build:mcp-bundle references in the README have been replaced with build:mcp, including in the "Bundle MCP into CLI" and "Building CLI package with bundled MCP server" sections. The surrounding descriptions have also been updated to accurately reflect what build:mcp does.
