Nabu Casa's prebuilt OpenThread RCP image for the ZBT-2
(zbt2_openthread_rcp_2.7.2.0_GitHub-fb0446f53_gsdk_2025.6.2.gbl)
runs at 460800 baud, not the module's 115200 default. Aligns the
radio URL with the firmware so otbr-agent can actually open the
Spinel link after rebuild.

Brings up otbr-agent against the ZBT-2 over Spinel/UART, opens the
REST API on :8081, and wires HA's otbr + thread integrations so
Matter-over-Thread devices can commission through the existing
matter-server.

Pulls the services.openthread-border-router NixOS module directly from
nixpkgs-unstable since it isn't in 25.11 yet. Service stays disabled
in this commit; configuration follows.
Also promotes `self` from `_module.args` to `specialArgs` in
machines/configuration.nix, since `imports` are evaluated before
`config` and so can't reach `_module.args.self`.

The original plan claimed no flake-level changes were needed because
machines/configuration.nix:21 already passes `_module.args.self = self;`.
That's only true for `config`-time evaluation; `imports` are collected
before `config` is available, so referencing `self` in `imports` causes
infinite recursion. Fix: promote `self` to `specialArgs` on each
nixosSystem call. The implementer of Task 2 caught this on first
dispatch.

Task-by-task plan covering: revert of prior ZHA commit, unstable
OTBR module import, OTBR enablement against the ZBT-2, firmware
flash via universal-silabs-flasher, rebuild on jupiter, and
end-to-end smoke test through the HA UI.
Designed for execution via superpowers:subagent-driven-development
or superpowers:executing-plans, with operator handoffs marked
explicitly (per the 'no SSH' workflow rule).

Captures the architecture, operator workflow, and verification for
running the Connect ZBT-2 as an OpenThread Border Router on jupiter
(via nixos-unstable's services.openthread-border-router module),
with HA's otbr + thread integrations driving the Thread network
and the existing matter-server consuming credentials for
Matter-over-Thread device commissioning.
Supersedes the ZHA-direction commit on this branch (e8d09f4),
which will be reverted at the start of implementation.

Adds the `zha` extra component so Home Assistant can drive the
Nabu Casa Connect ZBT-2 radio, and puts the `hass` service user in
`dialout` so it can open `/dev/serial/by-id/usb-Nabu_Casa_..._ZBT-2_*`.
Pairing is then handled through the standard ZHA wizard in the HA UI.

extraComponents only installs packages; mobile_app needs to be declared
in configuration.yaml to actually load.
