Use absolute path for PHPStorm and relative paths for others

What & Why

Developers can't commit the mcp files to git if they have absolute paths in, as each developer has a unique setup.

All IDEs seem to support relative paths, except PHPStorm. This PR updates our MCP registration so we use 'absolute' for PHPStorm/Junie, but 'relative' for every other IDe.

How I tested

1. boost:install and chose Cursor/PHPStorm
2. Checked the files

❯ grep artisan .junie/mcp/mcp.json .cursor/mcp.json
.junie/mcp/mcp.json:                "/Users/ashleyhindle/Code/scratch/flux-volt-folio-playground/artisan",
.cursor/mcp.json:                "./artisan",

Note

• Removed Zed also as it was getting messy and we randomly added MCP/guidelines to it, even though it never showed up in the options.
