feat(schema): generate app JSON Schemas from src/apps

[guitavano]

Summary

• Extend generate-schema.ts to scan src/apps/ (third pass after loaders and sections)
• Populate manifest.blocks.apps and schema.root.apps so the CMS can edit installed apps
• Skip helper files under site/apps/**/_* and support --skip-apps / --apps CLI flags

Test plan

• Run npx tsx scripts/generate-schema.ts on a site with src/apps/deco/vtex.ts bridge
• Verify meta.gen.json includes manifest.blocks.apps with VTEX entry
• Confirm existing section + loader generation unchanged

Summary by cubic

Generate JSON Schemas for app bridges in src/apps/ and expose them in manifest.blocks.apps and schema.root.apps. This lets the CMS edit installed apps (e.g., VTEX) without manual wiring.

• New Features

  • Adds a third pass to scripts/generate-schema.ts that scans src/apps/ and builds JSON Schema 7 for each app Props.
  • Populates manifest.blocks.apps and schema.root.apps.anyOf with refs to each app schema.
  • Skips helper files under /_*; adds --apps <dir> and --skip-apps flags.
  • Keeps section and loader generation unchanged; prints app counts in the summary.

• Migration

  • Run npx tsx scripts/generate-schema.ts to generate app entries.
  • Ensure app bridges export Props (interface/type or via default export) under src/apps/.
  • Verify meta.gen.json shows entries under manifest.blocks.apps.
