fix: remove non-existent wait_for_checks step from auto-merge

The become_user pattern with sudo doesn't reliably connect to the
user's D-Bus session, causing systemd user timers (docker-prune,
runner-healthcheck) to silently fail to enable. This led to stale
Docker images accumulating and filling the disk on CI runners.

Switch all systemctl --user invocations to use runuser with explicit
XDG_RUNTIME_DIR and DBUS_SESSION_BUS_ADDRESS environment variables,
which correctly connects to the user's systemd session.

Affected tasks: prune timer, healthcheck timer, gitea-runner service,
rootless Docker daemon start/enable/restart, runner service restart.

 All notable changes to this project will be documented in this file.
 
+## [Unreleased]
+
+### CI
+
+- Convert `ci.yml` and `post-merge.yml` to use composite actions
+  (`setup-env`, `quality-checks`, `notify-failure`) copied from devx,
+  reducing workflow duplication
+
+### Bug Fixes
+
+- Fix `register.yml` premature service start: removed step that ran
+  `systemctl --user start gitea-runner` before the systemd unit file was
+  created by `service.yml` (included after `register.yml`). First-time
+  installs were failing with "Unit gitea-runner.service not found".
+- Fix `ci.yml` auto-merge IndentationError: replaced broken inline Python
+  polling script with `devx.ci.wait_for_checks` (the inline Python had
+  YAML run-block indentation leaking into `python3 -c` string).
+
+### Dependencies
+
+- Bump devx from v0.50.0 to v0.50.5 (adds `wait_for_checks` tool,
+  consolidated Ansible checks, tenacity retry in `install_tools`,
+  increased download retry attempts/backoff)
+
+## [0.20.0] - 2026-08-09
+
+### Features
+
+- *(healthcheck)* Add two-tier disk prune with critical threshold

 `devx.molecule.distribute_molecule` discovers all molecule scenarios under `ansible/roles/*/molecule/` and crosses them with the supported OS platform matrix, then splits the resulting test pairs evenly across the requested number of runners. Each pair is encoded as `scenario|platform_name|platform_image|platform_command`.
 
-`devx.molecule.molecule_ci_guard` runs the actual molecule test for a given test pair, with CI context (Gitea URL, token, run ID) for reporting results back to the commit status API.
+The CI workflow runs each test pair sequentially via a shell loop that sets the appropriate `MOLECULE_PLATFORM_*` environment variables and invokes `molecule test` directly.
