feat: Rename interface-craft skill references to emilkowalski sources

[0xroylee]

What Changed

• Updated the startup-goal and web-design workflow manifests to use the upstream emilkowalski skill sources.
• Refreshed the corresponding lockfiles with new resolved names, hashes, and timestamps.
• Adjusted the skill installer mapping so emilkowalski sources are treated as canonical and interface-craft names remain compatibility aliases.
• Updated workflow, omniskill, CLI, and skill-installer tests to match the new source ordering and log assertions.

Why

• Aligns bundled workflows with the current upstream skill naming while preserving compatibility for legacy interface-craft references.
• Keeps installs and validation working across both naming schemes without changing workflow behavior.

How to Test

• Run the workflow bundle and installer test suites to confirm both canonical and legacy sources resolve correctly.
• Verify the updated workflow manifests still validate and produce the expected companion skill lists.
• Confirm CLI output assertions still pass for package install and plan flows.

Additional Notes

• This is a naming and compatibility update only; no workflow logic changed.
• Lockfile hashes changed because the resolved upstream skill identifiers changed.
• Not run (not requested)
