fix(template-generator): report correct dev port (3001) for tanstack-router (#1089)

The shared webPort formula in the README generator and the CLI
post-install note bucketed tanstack-router under 5173, but its
vite.config sets server.port: 3001. Every other place in the codebase
(vite configs, electrobun DEV_SERVER_PORT template, env-vars CORS/URL
logic) already treats tanstack-router as 3001, so both docs reported a
URL that didn't match the running dev server.

Remove tanstack-router from the 5173 bucket so it falls through to 3001.
