Restore approved state (tree of 4effcc7 "Added LICENSE")

Roll the working tree back to the last approved shape, before the post-LICENSE span that false-greened the AFI parity matrix with symbol-presence probes and smuggled an unauthorized SQLAlchemy dependency into FastAPI's Shapes binding.

Forward commit, not a history rewrite — the six commits since 4effcc7 stay in the log as the record of what happened.
