Replace scattered API_URL, MAIN_VITE_API_URL, and RENDERER_VITE_API_URL
with a single MULTICA_API_URL across all apps and packages.
- Desktop: use envPrefix to expose MULTICA_* to main process, rename
RENDERER_VITE_API_URL → RENDERER_VITE_MULTICA_API_URL, remove
MAIN_VITE_API_URL (now read directly via MULTICA_API_URL)
- Web: add .env.development with MULTICA_API_URL, enforce required check
in next.config.ts, update .gitignore to allow .env.development
- Core: make MULTICA_API_URL required in api-client (no silent fallback)
- Scripts: pass MULTICA_API_URL in dev-local.sh for web process
- Turbo: update globalEnv from API_URL to MULTICA_API_URL
- Docs: update references to the new env var name

Sets SMC_DATA_DIR=~/.super-multica-dev and
MULTICA_WORKSPACE_DIR=~/Documents/Multica-dev for gateway and
desktop processes in dev:local, preventing dev/prod data mixing.
