feat(local-deploy): replace supabase-js with direct postgres + autosync

[KainanYuval]

Summary

• Drop supabase-js from server/index.ts — replaced with npm:postgres@3 (direct TCP connection to Postgres), the same driver sync.ts already uses. No PostgREST / Supabase REST stack required.
• Remove cloud env vars (SUPABASE_URL, SUPABASE_SERVICE_ROLE_KEY, MCP_ACCESS_KEY). Connection is now driven by POSTGRES_URL (or individual POSTGRES_HOST / POSTGRES_PASSWORD / POSTGRES_DB vars), compatible with the ob1-postgres docker container out of the box.
• Add autosync loop — on startup and every 5 minutes (configurable via AUTOSYNC_INTERVAL_MS), the MCP server calls diffSince(cursor) to fetch only new Artifactory artifacts, upserts them via upsert_thought(), and generates embeddings only for rows where embedding IS NULL. Already-embedded thoughts cost zero Ollama calls.
• Stage artifactory.ts and sync.ts as tracked files (were previously untracked on this branch).
• Update deno.json — drop @supabase/supabase-js, add postgres@3.

Test plan

• POSTGRES_URL=postgres://postgres:ob1local@localhost:5432/ob1 deno task start — server listens on :8000
• Startup log shows [autosync] started — interval 300s and immediately runs a sync
• New artifact added to Artifactory appears in Postgres within 5 minutes with embedding
• Second sync run for the same artifact logs skipped embedding (already present) — no Ollama call
• All MCP tools (search, fetch, search_thoughts, list_thoughts, thought_stats, capture_thought) return correct results
