feat(db): commit initial migration SQL for production deployment

[diskhacker]

Summary

• server/src/db/migrations/0000_bizarre_the_hunter.sql (5.9 KB, 9 tables) — generated via pnpm db:generate. Required for db:migrate to work in production.
• server/src/db/migrations/meta/ — drizzle journal + schema snapshot.

Tables covered: signals, signal_rules, workflows, workflow_schedules, executions, execution_steps, agents, agent_tools, tool_registry.

Verification

• cd server && pnpm install && pnpm db:generate reproduces the SQL.

Test plan

• docker compose exec sigops-server pnpm db:migrate applies cleanly
• Re-running is a no-op

📝 Walkthrough

Walkthrough

This PR adds the initial database migration for an event-driven workflow execution system in PostgreSQL. It defines five ENUM types for status tracking and creates eight tables to manage agents, tools, executions, signals, scheduling, and workflows, along with B-tree indexes for query optimization and migration metadata snapshots.

Poem

🐰 A schema springs to life, so neat and bright,
With agents, tools, and signals taking flight,
Nine tables strong with indexes gleaming gold,
Our workflow engine now has roots to hold!
Enums stand guard where statuses reside—
The bunny's database, prepared with pride! 🌟
