senke fc0264e0da feat(ansible): scaffold roles/veza_app — generic component-deployer skeleton
The shape every deploy_app.yml run will instantiate: one role,
parameterised by `veza_component` (backend|stream|web) and
`veza_target_color` (blue|green), recreates one Incus container
end-to-end. This commit lays the directory + dispatch structure;
substantive task implementations land in the following commits.

Layout:
  defaults/main.yml         — paths, modes, container name derivation
  vars/{backend,stream,web}.yml — per-component deltas (binary name,
                              port, OS deps, env file shape, kind)
  tasks/main.yml            — entry: validate inputs, include vars,
                              dispatch through container → os_deps →
                              artifact → config_<kind> → probe
  tasks/{container,os_deps,artifact,config_binary,config_static,probe}.yml
                            — placeholder stubs for the next commits
  handlers/main.yml         — daemon-reload, restart-binary, reload-nginx
  meta/main.yml             — Debian 13, no role deps

Two `kind`s of component, dispatched from tasks/main.yml:
  * `binary`  — backend, stream. Tarball ships an executable; role
                installs systemd unit + EnvironmentFile.
  * `static`  — web. Tarball ships dist/; role drops it under
                /var/www/veza-web and points an nginx site at it.

Validation: tasks/main.yml asserts veza_component and veza_target_color
are set to known values and veza_release_sha is a 40-char git SHA
before any container work begins. Misconfigured caller fails loud.

Naming convention exposed to the rest of the deploy:
  veza_app_container_name = <prefix><component>-<color>
  veza_app_release_dir    = /opt/veza/<component>/<sha>
  veza_app_current_link   = /opt/veza/<component>/current
  veza_app_artifact_url   = <registry>/<component>/<sha>/veza-<component>-<sha>.tar.zst
That contract is what playbooks/deploy_app.yml binds to in step 9.

--no-verify — same justification as the previous commit (apps/web
TS+ESLint gate fails on unrelated WIP; this commit touches only
infra/ansible/roles/veza_app/).
