Make scripts/ a pnpm workspace + add README

render-legal.ts needs @types/node available to the TS language server
so editors (VS Code, cursor, etc.) don't complain about missing Node
globals. Without a tsconfig in this folder VS Code falls back to a
default config with no types and shows red squiggles on every
process/fs/path reference.

Solution: scripts/ becomes its own pnpm workspace (@trails-cool/scripts),
carrying @types/node as a devDep from the catalog, and a tiny
tsconfig.json with types: [node] and include *.ts. This also wires the
folder into `pnpm typecheck` as task #14, so CI type-checks scripts
alongside every other package. No runtime impact — the workspace is
never bundled or deployed.

README documents the layout, current contents (render-legal.ts +
check-dockerfiles.sh), and how to add new scripts.
