The gitea-branches skill was authored before the context7 research
backfill (workflow-conventions.md) landed on this branch, so its
sources.md was missing context7-websites-gitea and
context7-gitea-tea-cli — both present with status `extracted` in the
upstream research doc, which validate-provenance.sh requires every
consuming skill to account for. Adds context7-websites-gitea (credited
for the protected-branch gotcha) and context7-gitea-tea-cli (marked
`(none)` — its release/tag content is out of scope for branches/commits).
