Subject: [PATCH] Tag lib/ subpackages via TagBot matrix

Mirrors the NonlinearSolve.jl setup so each registered subpackage
under lib/ gets its own git tag/release on registration. Without
this, diffs and PR lists between versions of a given subpackage are
hard to recover because the monorepo only carried the top-level
OrdinaryDiffEq tag.
