feat(publisher): copy version from package.json and prefer mcpName in init

[JosephDoUrden]

Summary

Addresses two related enhancements to mcp-publisher init:

• Copy version from package.json (Make mcp-publisher init copy version from package.json #736): When package.json is present and contains a version field, it is now used for both the top-level version and packages[].version in the generated server.json. Falls back to "1.0.0" when unavailable. This aligns with the recommended best practice of keeping server version in sync with package version.

• Prefer mcpName over name (mcp-publisher init should prefer mcpName from package.json #737): The init command now checks for mcpName in package.json first, falling back to name if mcpName is not defined. This ensures the generated server name matches the required mcpName property.

Closes #736
Closes #737

Changes

• cmd/publisher/commands/init.go:
  • Added getVersionFromPackageJSON() helper to read version from package.json
  • Modified InitCommand() to use detected version with "1.0.0" fallback
  • Modified getNameFromPackageJSON() to prefer mcpName over name

Test plan

• go build ./cmd/publisher/... compiles without errors
• go test ./cmd/publisher/commands/... passes all existing tests
• Manual: run mcp-publisher init in a directory with package.json containing version and mcpName — verify both are copied to server.json
• Manual: run mcp-publisher init in a directory with package.json without mcpName — verify name is used as fallback
• Manual: run mcp-publisher init in a directory without package.json — verify defaults ("1.0.0", directory name) are used
