Unblocks CD: the build's go mod download failed because mcp-chassis was
imported via the old gitea.d-ma.be module path, which the renamed server no
longer serves a matching go-import meta tag for. Point at the renamed module
git.d-ma.be/mathias/mcp-chassis v0.2.0 (mcp-chassis 69d389d) + go mod tidy.
Fresh download now resolves; ingestion builds + tests green.
This restores the normal CI path so the routing pass-rate fix (da9bdc4,
#73) builds and deploys through gitea Actions. Refs #74, #73, #35.
