fix(release): point repository URLs at renamed GitHub repo (#250)

* fix(release): point repository URLs at renamed GitHub repo

The GitHub repo was renamed from Kaelio/ktx to
Kaelio/ktx-ai-data-agents-context. semantic-release reads repositoryUrl
from package.json's repository field and the @semantic-release/github
plugin failed verifyConditions with EMISMATCHGITHUBURL because it no
longer matched the live clone URL.

Update every Kaelio/ktx reference to the renamed repo: package metadata
(root + CLI repository/bugs/homepage), the codecov upload slugs and
star-history slug in CI, the issue-template and security-advisory links,
the release runbook, and all docs/install commands.

* fix(release): derive semantic-release repositoryUrl from the CI repo

@semantic-release/github exact-matches repositoryUrl against the live
GitHub clone_url (no redirect following), so any repo rename re-breaks the
release when repositoryUrl is the static package.json value.

Derive repositoryUrl from the runner's GITHUB_REPOSITORY/GITHUB_SERVER_URL
so it always tracks the current repo name. A future rename (including back
to Kaelio/ktx) now resolves with no code change. Outside CI the option is
omitted, so semantic-release falls back to package.json as documented.

The package.json repository field stays ktx-ai-data-agents-context as
npm-display metadata, decoupled from the release-time match.
