[Copilot]

This PR upgrades Prettier from version 3.3.3 to 3.6.0 across the entire monorepo.

Changes Made

• Root package.json: Updated prettier dependency from 3.3.3 to 3.6.0
• Template packages: Updated prettier version in all 20 template package.json files
• Test validation: Updated template validation test to expect prettier 3.6.0 instead of 3.3.3
• Lockfile: Updated pnpm-lock.yaml with new prettier version

Prettier 3.6.0 Features

This release includes several important additions:

• New experimental high-performance CLI behind --experimental-cli flag
• Two new official plugins: @prettier/plugin-oxc and @prettier/plugin-hermes
• Various performance improvements and bug fixes

Validation

✅ All template validation tests pass with new prettier version
✅ Stylecheck passes for all packages (excluding docs as requested)
✅ Prettier API functionality verified in studio-server codemods
✅ No formatting changes required - 3.6.0 produces same output as 3.3.3 for current codebase

The upgrade maintains full backward compatibility while providing access to the latest Prettier improvements and features.

Fixes #5460.

@copilot use the new experimental cli option

Implemented the experimental CLI flag across all prettier usage in the monorepo. Updated 48 package.json formatting scripts, the google-fonts update script, and copilot instructions to use --experimental-cli. All tests pass with the new high-performance CLI. 672037d
