@W-19624822 feat: eliminate the extra parameters exposed through create_page tool

[sf-henry-semaganda]

Description

Refactored the create_page tool to eliminate 5 parameters (nodeModulesPath, componentsPath, pagesPath, routesPath, hasOverridesDir) from its interface, reducing it from 8 to 3 essential parameters.

Types of Changes

• Bug fix (non-breaking change that fixes an issue)
• New feature (non-breaking change that adds functionality)
• Documentation update
• Breaking change (could cause existing functionality to not work as expected)
• Other changes (non-breaking changes that does not fit any of the above)

Breaking changes include:

• Removing a public function or component or prop
• Adding a required argument to a function
• Changing the data type of a function parameter or return value
• Adding a new peer dependency to package.json

Changes

• Created a detectWorkspacePaths() function that automatically detects all required paths using the PWA_STOREFRONT_APP_PATH environment variable, making the tool work seamlessly across both monorepo and generated projects.

How to Test-Drive This PR

• Build the MCP package first: cd packages/pwa-kit-mcp && npm run build
• Test in monorepo: Use your existing MCP config with PWA_STOREFRONT_APP_PATH pointing to the monorepo app directory
• Test in generated project: Create a new MCP config and try creating a page

LGTM, but if we merge directly to develop then a changelog is required
