Remove camel:core from the Kamelet dependencies: every Camel runtime has it #3096

Claude Code on behalf of Claus Ibsen.

162 of the 259 Kamelets on main list camel:core in spec.dependencies. The other 97 leave it out and work the same way, because every Camel runtime has camel-core. So the entry adds nothing, and it is inconsistent across the catalog.

camel:kamelet is different: it is the camel-kamelet artifact that runs the template, not part of camel-core. All 259 Kamelets list it, and it should stay.

Why it matters now:

• Models learn from this catalog. They copy the entry into the Kamelets they write.
• The Camel AI tools will note camel:core in a Kamelet file as implied (CAMEL-25403: camel-jbang - AI tools: note a Kamelet camel: dependency that the template does not use camel#27473, CAMEL-25403). That note is a hint, not an error, but the catalog should follow it.

Proposal:

• Remove the camel:core line from the 162 Kamelets, in the kamelets/ sources and the library copies.
• Regenerate the catalog SBOM.
• The change is mechanical. It is one PR if wanted.
