fix: resolve CLI entrypoint routing issue

[mrsimpson]

Two key fixes:

1. Replace pnpm workspace protocol dependencies with fixed version numbers:

   • Convert 'workspace:*' to '1.0.15' for @codemcp/knowledge-core, @codemcp/knowledge-content-loader, and @codemcp/knowledge
   • This allows the package to be installed via npm without errors
   • Fixes: EUNSUPPORTEDPROTOCOL 'workspace:' error when installing from registry

2. Remove duplicate bin field from @codemcp/knowledge (MCP server) package:

   • MCP server package.json had 'bin' field pointing to its bin.js
   • Root package.json already defines the correct CLI entrypoint
   • When both packages define the same bin name, npm installs the wrong one
   • Removing the bin field from sub-packages ensures root package controls routing

This ensures that 'npx agentic-knowledge-mcp create' correctly routes to the CLI instead of starting the MCP server. The routing logic in packages/cli/src/index.ts now works correctly:

• No args: starts MCP server
• With args: delegates to CLI commands
