feat(registry): add hirael to directory

[MohammadShehadeh]

Adds @hirael to the community registry directory (apps/v4/registry/directory.json),
following the registry index format at https://ui.shadcn.com/docs/registry/registry-index

Entry

Field	Value
name	@hirael
homepage	https://hirael.com
url	https://hirael.com/r/{name}.json

Notes

• Inserted in alphabetical order, between @hextaui and @iconiq.
• The logo uses currentColor, so it renders correctly in both light and dark themes of the directory UI
