dev: one-command local stack via dev.sh

Browse source 
Starts the Go API and the Vite dev server as background jobs; 'wait -n'
returns when the first one exits and the EXIT trap kills the rest, so
one Ctrl-C (or either server crashing) stops everything. Installs
web/node_modules on first run. Verified: both ports respond, SIGINT
leaves no orphan processes.

## Development
Two terminals:
One command (installs frontend deps on first run, Ctrl-C stops everything):
```sh
./dev.sh
```
Or manually, in two terminals:
```sh
go run ./cmd/spreadlab # API on localhost:8080
