On a fresh clone the vendored third-party lexicons (lexicons/{app,com, tools,games}) are gitignored and absent, and `make lexicons` ran Go codegen before anything fetched them — so `make ci-lexicons` failed in CI with "schema not found in catalog: app.bsky.actor.defs#profileViewBasic". Run `glex install` (manifest-pinned) first. Also store lexicons.json exactly as the tools write it (no trailing newline) — the previous newline fix got rewritten by every install, which would trip ci-lexicons' git-diff check; prettier now ignores the file instead.
