feat: parity — brightness, window switch, spelling, network, summarize (100 commands)

Mirrors the rust tier-3 batch. 90 → 100 commands (round number — feels
right for an "имба" milestone).

main.py:
+ do_brightness: WMI WmiMonitorBrightness read + WmiSetBrightness write,
  ±20% step or 100/10 absolute, "no_wmi" sentinel for desktops.
+ do_window_switch: same alias map as process_kill (xrom→chrome/...),
  PS finds process by name OR window-title substring, picks newest
  StartTime, AppActivate via WScript.Shell.
+ do_spell_out: split chars, join with ". ", _speak.
+ do_network_settings: action.section = wifi|bluetooth|network →
  matching ms-settings:* URI via cmd /c start "".
+ do_my_ip: Get-NetIPAddress filtered to non-loopback non-APIPA IPv4,
  WAN via Invoke-RestMethod ipify, speaks "Локальный X. Внешний Y".
+ do_summarize_selection: pyautogui.hotkey(ctrl, c) → 250ms wait →
  Get-Clipboard → Groq @ temp 0.3 ("3-5 sentence retell") → speak +
  clipboard.

commands.yaml +10 entries: brightness_up/down/max/min, switch_to_window,
spell_out, open_wifi_settings, open_bluetooth_settings, my_ip,
summarize_selection.

Backlog: closed all "Tier-3 still TODO" pure-Lua items. Remaining
TODOs (pomodoro, currency-math, stocks, translate-clipboard, daily
briefing, etc.) are even smaller LOC and can roll in the next batch.
