chore: trigger CI after branch rename to DEVX-153

The v0.49.x tag line diverged from origin/master, leaving many
features only accessible via tags but not on the master branch.

New modules:
- ci/cancel_superseded_runs.py — cancel superseded CI runs
- ci/check_workflow_artifact_deps.py — validate artifact deps
- ci/check_workflow_tofu_init.py — validate tofu init steps
- tools/check_alert_rules.py — validate Prometheus alert rules
- tools/check_ansible_set_fact_to_json.py — lint set_fact usage
- tools/check_docker_init.py — validate Docker init scripts
- utils/jinja.py — Jinja2 template utilities
- utils/ui.py — UI/console utilities

Modified modules:
- distribute_molecule.py: add --include-roles/--exclude-roles
- utils/api.py: add container.credentials for private registry auth
- install_tools.py: retry ansible-galaxy on transient timeouts
- setup_image.py: skip dep resolution with --no-deps
- cli.py: register new commands
- i18n.py: add new translation keys

Also removes accidentally committed .vale/styles/Google/ files.

Test results: 2195 passed, 100% coverage.

+The check scans all workflow YAML files for:

+  - ``gitea-download-artifact`` / ``actions/download-artifact`` steps

+For each download, it finds the job(s) that upload an artifact with a

+"""Check that Ansible ``set_fact`` tasks don't misuse ``| to_json``.
+
+This prevents the class of bug where ``set_fact`` tasks use
+``{{ targets | to_json }}`` to store Python lists, but ``to_json``
+converts native types to JSON strings. Ansible then stored the result
+as a string, so iterating over the fact yielded individual characters
+instead of list items, causing ``object of type 'str' has no attribute
+'ip'`` errors.
+
+The check scans all Ansible task files (playbooks and role tasks) for

+and flags them as potential bugs.
+

+store the native Python type so downstream tasks can iterate/index it.

+"""Check that Docker Compose services with healthchecks have ``init: true``.
+
+This prevents zombie process accumulation on production VMs. Without
+``init: true``, Docker uses the container's PID 1 process to reap
+child processes. Many images (especially those using CMD-SHELL
+healthchecks with ``wget``) don't call ``wait()`` on children, causing
+zombies to accumulate.
+
+The check scans all Jinja2 docker-compose templates for services that
+have a ``healthcheck:`` key but no ``init: true`` key. Since the
+templates use Jinja2 syntax (not pure YAML), the check uses text-based
+parsing to identify service blocks and their properties.
+
+Usage::
+
+    python -m devx.tools.check_docker_init
+    python -m devx.tools.check_docker_init --path ansible/roles/observability/templates/docker-compose.yml.j2
+
+Exit code 0 if all services with healthchecks have init: true, 1 otherwise.

+CI runner scaling
+-----------------
+CI runners (Gitea Actions Docker containers) are typically 5-8x slower than
+local development machines due to shared CPU, fewer cores, and container
+overhead.  When the ``CI`` environment variable is set (standard CI
+convention), both the total and per-test limits are multiplied by
+``CI_SCALE_FACTOR`` (default 6) to account for this.  This keeps the local
+budget strict while preventing false failures on slower CI runners.
+
+The scale factor can be overridden via the ``DEVX_CI_SCALE_FACTOR``
+environment variable.
