Ecosystem page: current public implementations and published artifacts

[styk-tv]

Goal

The docs should point readers at the current public implementations and artifacts of the protocol, so “reference authority” includes where to run it today.

Current public surface to reference

• styk-tv/pgCK — the Concept Kernel runtime (PostgreSQL extension), latest published extension v0.4.15 as an attested OCI artifact (see its LATEST.md for verified digests)
• ConceptKernel/CK.Lib.Js — cklib, the JS client speaking ckp.dispatch over NATS-WSS, latest v1.5.3; npm publication is tracked in npm go-live: publish 1.5.3 as latest; neutralize legacy 1.0.0 CK.Lib.Js#4
• sporaxis-com/oci-germination — runnable bundles and the hello-kernel example (zero-to-sealed-state, Docker only) that pgCK's README already links
• sporaxis-com/sporaxis — ontology-first OCI bundle assembler; fleet adoption tracked in sporaxis-com/sporaxis#12
• styk-tv/pgRDF — the RDF/SPARQL/SHACL substrate the runtime builds on

Tasks

• Add/refresh an ecosystem page in the v3.9.1 set with the table above (versions verified against each repo's LATEST.md at time of writing)
• Link the runnable hello-kernel path as the canonical “see it in 30 seconds” for the site
• Establish the convention: the site names public repos and published artifact versions only; per-repo release detail stays in each repo's own LATEST.md

Shipped. The ecosystem page is live at https://conceptkernel.org/v3.9/ecosystem — a table of the current public fleet with shipped versions (pgCK v0.4.17, cklib v1.5.3, pgRDF v0.6.19, sporaxis v0.0.5, oci-germination ck-allinone v0.7.25), the LATEST.md-per-repo convention, and the SLSA-attested/verified-before-publication note.
