chore: revert repo references to Kaelio/ktx and remove rename-resilience (#252)

The GitHub repo was renamed back from Kaelio/ktx-ai-data-agents-context to Kaelio/ktx, reverting the URL changes from #250 across package metadata, CI (codecov + star-history slugs), issue/security templates, the release runbook, and docs/install commands.

Also removes the rename-resilience machinery #250 added: semantic-release now reads the repository URL straight from package.json (Kaelio/ktx) again, so the repositoryUrl() derivation in scripts/semantic-release-config.cjs, its tests, and the rename note in docs/release.md are no longer needed.
