[codex] Update bundled intake visual spec package

[bigsmartben]

Summary

Sync the bundled extensions/intake snapshot in the fork repository with the latest bigsmartben/spec-kit-intake source after merging PR #4 there.

What changed

• Updates the bundled intake extension to use /speckit.intake.visual-design as the single visual intake entrypoint.
• Removes bundled /speckit.intake.figma2htmlssot and /speckit.intake.ir command surfaces.
• Adds the visual spec package artifact family and preview coverage helper contracts, schemas, validators, and tests.
• Updates fork README, extension catalogs, community docs, and bundled default command expectations to remove old HTML SSOT / structured IR intake references.

Why

The intake target is now the visual requirements/spec structured asset package. Component matrix previews remain helper evidence for reviewer coverage, not target implementation HTML or a separate intake command.

Validation

• pytest -q extensions/intake/tests/test_extension_contract.py -> 70 passed, 1 skipped
• PYTHONPATH=src pytest -q tests/integrations/test_manifest.py tests/integrations/test_integration_catalog.py tests/integration/test_bundler_catalog_stack.py tests/test_extensions.py tests/test_extension_registration.py -> 492 passed, 9 skipped
• git diff --check --cached -> passed

Source

• Source repo merge: [codex] Add visual spec package intake spec-kit-intake#4
• Source commit synced: ee785908286e4110e42e05f3937c750602b99ae1

[bigsmartben]

Closing because this downstream fork PR should not be used to merge the upstream/source intake change path.

Remove the BOM from the command frontmatter

When this extension command is registered, CommandRegistrar.parse_frontmatter() only recognizes command metadata when the file content starts with ---; the leading U+FEFF here means this command is treated as having no frontmatter. Projects that install the intake extension will generate agent commands/skills for speckit.intake.visual-design without the intended description and with the raw frontmatter block left in the prompt body.
