Extract pushWithSync() helper to eliminate boilerplate across 6 push
functions. Add pushHeartbeat() for connectivity testing. Add push-greptile
to CLI. New commands: gstack-sync test (validates full push/pull flow
via sync_heartbeats table), gstack-sync show (terminal team data
dashboard with summary/evals/ships/retros views). Guard main block
with import.meta.main.

- lib/sync-config.ts: reads .gstack-sync.json + ~/.gstack/auth.json
- lib/auth.ts: device auth flow (browser OAuth, local HTTP callback)
- lib/sync.ts: Supabase push/pull via raw fetch(), offline queue, cache
- lib/cli-sync.ts: CLI handler for gstack-sync commands
- bin/gstack-sync: bash wrapper (setup, status, push-*, pull, drain)
- .gstack-sync.json.example: template for team setup
Zero new dependencies — uses raw fetch() against PostgREST API.
All sync is non-fatal with 5s timeout and offline queue fallback.
