Prepare current GitHub URLs for the owner-selected username artificenerd.

Draft: merge only after Felipe confirms the GitHub account has changed from coisa to artificenerd. This PR does not rename the account, migrate Composer package names/vendors or PHP namespaces, modify locked dependency metadata, publish packages, or change organization owners.

Existing composer-skeleton repository suffixes are preserved; availability of that repository needs to be reconciled separately.

Validation:

• git diff --check HEAD^ HEAD passed.
• Exact substitution check passed for all changed files: only the personal GitHub URL owner changed (plus trophy/metrics identity for the profile repository).
• Existing Composer package names, autoload mappings, and dependency requirements are unchanged; JSON parses successfully where present.
• Workflow trigger inspection found no release/package/site publication on this feature branch push or PR. Existing default-branch publication behavior is retained.
• PHP/Composer are unavailable in this preparation environment; no runtime suite result is claimed. Check repository CI before eventual merge.

After the account change: confirm branch/base identity and CI, merge when authorized, then verify repository URLs, integrations and local remotes. Package/vendor/namespace migration requires a separate compatibility plan.
