POC: lift the homelab-grown nextcloud-mcp-server and nextcloud-mcp-deployer-role Terraform modules into this repo so external operators can consume them via a `git::` source. Includes a top-level README documenting the two-phase deploy flow (bootstrap deployer role with a copy-pasteable IAM policy, then assume the role to deploy the MCP server) and supports both in-VPC Qdrant and external/managed Qdrant modes.
