feat: adding project-discovery-worker (CM-949)

[ulemons]

Summary

This PR introduces the basic structure for the new worker.

The implementation includes the foundational setup required to run the worker, without full business logic.

Included

• Worker initialization and configuration
• Base execution flow
• Placeholder structure for future processing logic

⚠️ This is just the basic structure of the worker, i won't probably merge this before the other prs of the POC will be completed

---

Note

Medium Risk
Adds new database tables/indexes and introduces a new Temporal-scheduled worker service; migration/infra changes can impact deploys and scheduling behavior if misconfigured.

Overview
Adds the initial automatic projects discovery foundation: a new Temporal worker app that registers a cron schedule (env-configurable, default daily) to start a discoverProjects workflow and run a placeholder activity.

Introduces new DB schema for discovery/evaluation via migrations creating projectCatalog and evaluatedProjects tables (with uniqueness and query indexes) plus a matching down migration, and adds Docker/compose build+run wiring for the new worker along with pnpm-lock.yaml workspace entries.

[Copilot]

pnpm-lock.yaml contains two importers for this new app: services/apps/automatic_projects_discovery_worker (correct) and services/apps/automatic_project_discovery_worker (missing the s in projects). The latter path doesn’t exist in the repo and will leave the lockfile in an inconsistent state (pnpm will warn/error depending on settings). Please regenerate or edit the lockfile so only the correct importer remains.

Stale workspace importer in lockfile

Medium Severity

pnpm-lock.yaml adds an importer for services/apps/automatic_project_discovery_worker, but that workspace path is not present while the real app is services/apps/automatic_projects_discovery_worker. This leaves a stale duplicate importer in the lockfile, creating an inconsistent workspace definition that can destabilize pnpm install --frozen-lockfile behavior and dependency maintenance.

throw new Error(err) loses original error context

Low Severity

throw new Error(err) wraps the caught err (likely already an Error) inside a new Error, which discards the original stack trace, error type, and any custom properties. The resulting error message will be the stringified version of the original error (e.g., "Error: ...") rather than the original message. Rethrowing err directly would preserve all original context, making debugging much easier.
