Dated project introductions

Authored dates come from the exact registration’s first content commit, PR dates identify when work was proposed to each project, and integration dates come from each first-parent mainline. A project merging first does not override earlier upstream authorship or submission.

Later changes

These commits occur after the ultimate-origin introduction on TaystJK’s inherited first-parent lineage. Registration evidence is exact; behavior evidence requires a changed bound cvar reference or a changed registered command-handler hunk.
