chore: drop pyright/pylint badges and their badge-update automation

The pyright "0 errors" and pylint "9.93/10" badges were static,
hand-synced shields that duplicated state the `lint` CI job already
enforces — a maintenance tax that could silently drift from reality.
Remove both badges from the README and strip the corresponding steps
(pylint/pyright runs, sed rewrites, commit-message lines, and the
`.pylintrc`/`pyrightconfig.json` path triggers) from the badge-update
workflow. Lint/type enforcement in CI is unchanged; only the published
badges go away. Coverage and core-coverage badges stay.
