devcontainer: pin compose project name to note-arduino-notestation#163

Conversation
The devcontainer CLI derives the Docker Compose project name from the
directory name of the devcontainer.json file -- in this case 'notestation'.
Every Blues SDK repo uses the same folder name, so running two notestation
devcontainers simultaneously causes a project name collision: Docker Compose
sees the existing project and (with --no-recreate) reuses the wrong
containers and workspace mount.
Fix: use the Compose Specification 'name:' field to hard-code a unique
project name ('note-arduino-notestation') that is independent of the
directory. The devcontainer CLI respects this field and will not override
it with the derived name.
Also drops the deprecated 'version:' key in favour of plain Compose
Specification format.
Requires Docker Compose v2 (the 'docker compose' plugin). Docker Compose
v1 ('docker-compose') does not support the 'name:' field.

Problem
The devcontainer CLI derives the Docker Compose project name from the directory name of the
devcontainer.jsonfile — in this casenotestation. Every Blues SDK repo uses the same.devcontainer/notestation/folder convention, so running two SDK notestation devcontainers simultaneously causes a project name collision.Concretely, the CLI invokes:
With
--no-recreate, if another SDK's notestation containers are already up under thenotestationproject, Docker Compose reuses them — attaching to the wrong workspace and image.Fix
Use the Compose Specification
name:field to hard-code a unique project name (note-arduino-notestation) directly in the compose file. The devcontainer CLI respects this and will not override it with the directory-derived name.The deprecated
version:key is also removed, as it is not used by the Compose Specification.Requirements
Docker Compose v2 (
docker composeplugin). Docker Compose v1 (docker-compose) does not support thename:field.Related
The same fix is being applied to note-posix and should be rolled out to all Blues SDK repos that ship a
notestationdevcontainer.
