feat(audio,menu): dock audio auto-follow watcher + docked Display/Audio menu rows

Bernardo's dock test (the #87 V3): audio stayed on EasyEffects→speakers.
Root cause, established live: WirePlumber's stored default
(default-nodes state, written by any past explicit pick) outranks the
priority.session rules, so #87 alone can never move the default on a
real machine; EasyEffects 8 follows the default device (kcfg default
true, verified by watching its output links). Fix: nomarchy-dock-audio
(modules/home/dock-audio.nix, nomarchy.dockAudio.enable, default on) —
a pactl-subscribe watcher that set-default-sinks new dock-class sinks
(regex data imported from modules/nixos/dock-audio-rules.nix, single
source) with a toast, plus a startup sweep for login-while-docked that
never overrides a manual in-dock pick. Unplug falls back by priority.

Menus: Display gains docked rows — "Laptop screen off · everything →
<ext>" (live-only disable; a persisted one could black-screen an
undocked boot), "Screen on · <name>", "Move workspace · → next
monitor", "Swap workspaces" (exactly-2 gate); Audio gains a self-gated
"Send output → <dock sink>" quick row. All self-gate on real outputs.

Verified: V2-equivalent on live hardware (no dock available) — watcher
followed a fake dock-named null sink and fell back on unload, control
run without the watcher stayed pinned (proving the stored-default
diagnosis), EE output links moved mid-playback; generated menu bash -n
green, dock-row jq exercised on real pactl JSON, dispatchers probed on
live Hyprland; flake check + option-docs + template-sot green.
V3 pending: real-dock retest ×2 in HARDWARE-QUEUE (watcher keys on
new-sink events; pre-existing nodes that only flip route availability
would need the queued diagnosis data).

+- [ ] **#87 round 2: dock audio auto-follow (watcher)** — round 1 result
+      (Newton, 2026-07-12): audio stayed on speakers when docking; the
+      running generation had no `90-nomarchy-dock-audio` rules yet, and
+      live testing showed the priority rules alone can never win anyway —
+      WirePlumber's stored default (`default-nodes` state, written by any
+      past explicit pick) outranks `priority.session`, and this machine
+      (like most) has one. Fix shipped: the `nomarchy-dock-audio` user
+      service `pactl set-default-sink`s dock-class sinks on hotplug;
+      EasyEffects follows the default (verified live: EE's output links
+      moved to a fake dock-named null sink mid-playback). Retest after
+      pull+rebuild+home on ≥ this rev: play audio, plug the dock →
+      toast "Audio → <monitor/dock>" and sound moves with EE effects
+      still active; unplug → sound returns to speakers; while docked,
+      picking speakers in the Audio menu sticks until the next replug.
+      If it does NOT switch, capture for diagnosis: `pactl subscribe`
+      output during the plug, `pactl --format=json list sinks` while
+      docked (sink names may not match the dock regexes, or the sink
+      node may pre-exist and only flip route availability — the watcher
+      keys on new-sink events).
+- [ ] **Docked display/audio menu rows** (2026-07-12) — with a real

+      everything → <ext>" (only with >1 active output), "Screen on ·
+      <name>" after a disable, "Move workspace · → next monitor", "Swap
+      workspaces" (exactly 2 outputs). Laptop-off must move its
+      workspaces to the external; Screen on restores it (preferred/auto —
+      declared scale/pos return at the next relogin/switch). Audio menu
+      shows "Send output → <dock sink>" when one exists and isn't
+      default; picking it moves output + toasts. Pass = rows appear/act
