refactor!: remove legacy adapters, policy engine and API-key auth

Removes the FastAPI server, hand-rolled MCP protocol, tool registry and
tools, YAML policy, resource-type authz, API-key and OAuth proxy modules,
automation, observability, cache, the old Gitea client and stdio adapter,
the key-management scripts and their tests (ADR 0006).
