Moves the six backend projects on disk into Core/ and Hosts/
subfolders, matching the solution folders already defined in
Musify.slnx, so the file explorer reflects the same layout as the
solution:
backend/Core/Musify.Domain
backend/Core/Musify.Application
backend/Core/Musify.Infrastructure
backend/Hosts/Musify.Api
backend/Hosts/Musify.Worker
backend/Hosts/Musify.StreamingGateway
Updates every reference to the old paths: ProjectReference entries in
Musify.Api.csproj and Musify.Worker.csproj, the three Dockerfiles,
deploy/scripts/migrate.ps1|sh, deploy/zitadel/provision.ps1,
deploy/up.ps1, deploy/README.md and docs/development.md. Also fixes a
stale Dockerfile comment pointing at a compose file that no longer
exists.
Verified with `dotnet build Musify.slnx` against the new layout.
Production had no orchestrator at all and its provisioning script required
PowerShell 7 on the server. up.sh now does the whole thing in POSIX shell:
it refuses to start until .env.prod and the origin certificate are in place,
generates the stream keys, brings up the infrastructure and the edge,
provisions Zitadel, applies the migrations and finally builds and starts the
applications. It is idempotent, so the same command deploys a new version.
provision.sh replaces provision.prod.ps1 (curl + jq) and also creates the web
player client, and migrate.prod.sh moves to scripts/migrate.sh reading the env
file with a parser instead of sourcing it as a shell script.
