v0.1.3

Every install form now ships the same code: the built halves are committed, so dsh plugin add github:JochenYang/dsh-rewind-plugin needs no build step (pnpm refuses to run a git dependency's build script unless the profile allowlists it). prepublishOnly still rebuilds before every registry release.

The readme the npm page renders is the corrected one: centred header and real install commands.
