First project discovery

First discovery creates a reviewable baseline before feature work begins.

1. Detect repository and monorepo boundaries.
2. Select colocated, centralized, or root-only workspace placement.
3. Record shared trackers, architecture sources, project boundaries, and database metadata.
4. Build local driver capabilities from the tools available on this machine.
5. Configure read-only probe profiles outside tracked project artifacts.
6. Generate source-bound discovery evidence and request human review.

Shared facts are committed. Credentials, provider sessions, leases, caches, and per-machine driver choices stay local. Re-running discovery reconciles new projects and changed evidence instead of duplicating the workspace.

Continue with feature delivery after the baseline is accepted.
