Slim tunnels localhost with clean HTTPS

Slim is the kind of boring-looking infrastructure tool that quietly saves hours; it wins by deleting the glue work between “runs on my machine” and “usable by someone else.”

• –Trusted local certs and automatic hosts entries make HTTPS feel native instead of bolted on.
• –`slim share` adds public URLs with password protection and TTLs, which is cleaner than ad hoc tunneling for quick demos.
• –Path routing and `.slim.yaml` make multi-service apps easier to reproduce across a team.
• –Built-in websocket and HMR support matters because modern dev stacks often break first at the proxy edge.
