The /_tuwunel namespace carries Tuwunel's ad-hoc routes (server_version,
local_user_count) and its native OpenID Connect provider endpoints
(/_tuwunel/oidc/...), which a reverse proxy must route for OIDC login
to work. Add public (enabled by default, like the client API) and
internal Traefik label groups.

Tuwunel serves the Synapse administration API under /_synapse/admin,
but the role only routed /_matrix, so admin dashboards and moderation
bots could not reach it. Add public and internal Traefik label groups
mirroring the matrix-synapse role, and enable them automatically when
Ketesa, Element Admin, or Draupnir is installed.

`agru` likes to open a TUI by default and shows what is done there,
then auto-closes and you don't get to see what it did.

LiveKit Server configuration validation now requires an explicit choice
between an RTC port range and a multiplexed UDP port, instead of
silently rendering the default udp_port alongside a user-defined port
range (which LiveKit ignores). See the CHANGELOG entry for details.

Points AI coding agents at the new style guide and summarizes the
repository layout and the conventions that are easy to get wrong
(roles/galaxy being auto-managed, group_vars wiring boundaries,
variable deprecation).

Codifies the conventions the playbook and its documentation already follow:
language and Markdown style, placeholder values for examples, the structure
of component documentation pages, and the checklist for adding a new
component (including where a component should live: this playbook, an
external MASH role, or mash-playbook).

Fixes #3631

The exporter's configuration used to ship a leftover "myprefix" placeholder
as the metric name prefix, so the bundled Grafana dashboard (which queries
unprefixed metric names) could never show any data.

Metric names are now unprefixed and the namespace label value changed from
matrix to nginx. See the CHANGELOG entry for details.

Fixes https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/3380

A single prefix-level catch in matrix_playbook_migration covers all
renamed bridge variable prefixes at once. It always runs (unlike the
per-role validate_config tasks, which only run when a role is enabled),
so a stale old-style _enabled variable cannot silently disable a bridge.

Renames the matrix_mautrix_SERVICENAME_* placeholders in the common
mautrix bridges guide to matrix_bridge_mautrix_SERVICENAME_*, and fixes
prose in the matrix-bridge-steam role that referred to the old variable
prefix and to a misspelled (underscore-styled) systemd service name.

The companion appservice variables defined by this role are folded
under the role prefix as well: matrix_mautrix_androidsms_* becomes
matrix_bridge_mautrix_wsproxy_androidsms_* and matrix_mautrix_imessage_*
becomes matrix_bridge_mautrix_wsproxy_imessage_*.

matrix_mautrix_signal_wsproxy_syncproxy_connection_string becomes
matrix_bridge_mautrix_wsproxy_syncproxy_connection_string, aligning it
with the sibling matrix_bridge_mautrix_wsproxy_syncproxy_* variables.
