Slot assignment goes back into worktree-env: it had one caller, and the herdr plugin it was extracted for provisions worktrees before the checkout is usable, so it carries its own copy rather than sourcing one whose contents depend on whichever branch the main checkout sits on. Writing .env.local stays shared - worktree-env and post-create.sh each had the same eleven lines. Also corrects AGENTS.md: .env.local is a shared format rather than a shared function, and WM_DB_NAME comes from it rather than webmux's runtime.env.
