feat(commands): analog-inspired tier-2 — news, currency, crypto, fun, wiki, power, help (33 packs)

Seven more portable Lua packs lifted from common voice-assistant
playbooks (Siri/Alexa/Алиса/Cortana). All sandbox=full, jarvis.http
+ jarvis.system.exec, zero new Rust code. cargo test still 3/3.

news/ — pulls Lenta.ru RSS (en switches to BBC), regex-extracts the
top 5 <title> entries (skipping the channel header), drops them into
the clipboard, then asks Groq for a 2-3 sentence summary at temp 0.4
and speaks it via SAPI. If GROQ_TOKEN is missing it falls back to
just reading the first three headlines.

currency/ — cbr-xml-daily.ru/daily_json.js. Picks USD/EUR/CNY/GBP/
JPY/KZT by keyword in the phrase, computes value / nominal, diffs
against Valute.Previous, says "X стоит N рублей, поднялся/опустился
на M" with ▲/▼ in the notify body.

crypto/ — CoinGecko simple/price with usd,rub and 24hr_change.
Recognises bitcoin / ethereum / solana / dogecoin / the-open-network.
Reports price + direction in plain Russian.

fun/ — joke / fact / quote / compliment, single ask.lua dispatched by
command_id. Per-command system prompt at temp 1.0; seeds with a
random integer so consecutive calls don't repeat.

wiki/ — ru.wikipedia opensearch → REST summary endpoint. If Groq is
available and extract > 350 chars, asks for a 2-3 sentence retell;
otherwise speaks the first 400 chars verbatim. Full extract goes to
clipboard.

power/ — shutdown_pc / restart_pc / sleep_pc / hibernate_pc /
logoff_user / cancel_shutdown. Single act.lua keyed by command_id.
shutdown/restart use shutdown.exe /s|/r /t 30 with a /c message —
30-second grace window so "отмени выключение" actually works.
sleep uses rundll32 powrprof,SetSuspendState, hibernate uses
shutdown.exe /h.

help/ — "что ты умеешь". Reads the parent commands/ dir via
jarvis.fs.list, sorts subdirs (pack names), pairs each with a
hardcoded Russian/English one-liner description, copies the full
list to clipboard and speaks a count + "see clipboard for full list".

Total command packs is now 33 (was 26).
