feat: Wave 5 — sysinfo speaks, smart reminders, outlook COM, time tracker, WOL, conversation tools

Voice sysinfo overhaul (6 scripts: battery/cpu/ram/disk/time/all):
- Now SPEAK the result via jarvis.cmd.ok instead of notify-only. Toast
  still fires for visual reference, but real Jarvis tells you out loud.
- `all` joins lines with commas so TTS doesn't over-pause on linebreaks.

Smart reminders (`reminders/set.lua` rewrite):
- Was: detached `Start-Sleep` PowerShell subprocesses that died on
  jarvis-app restart and spawned a hidden process per timer.
- Now: routes through `jarvis.scheduler.add(... type=speak ...)`. Persists
  to schedule.json, survives restart, no zombie processes. Trade-off:
  sub-minute timers round up to 1 min (rare in voice UX).
- Drops UA triggers from earlier UA-removal sweep.

Translation polish (`translate/translate.lua` + `clipboard.lua`):
- Drops UA target language; adds Italian, Polish, Turkish, French ru
  triggers + English target detectors.
- `language_iso()` helper picks the SAPI voice locale for the TARGET
  language (German translation → German SAPI voice if installed).

LLM system prompt (config.rs):
- New LLM_SYSTEM_PROMPT_EN counterpart. Both languages now mention the
  assistant's tooling (memory / scheduler / profiles / macros / vision /
  clipboard) so the LLM knows it can DO things, not suggest the user
  install something.
- `get_llm_system_prompt(lang)` picks EN/RU.

Conversation pack (NEW `conversation/`):
- 2 commands. `conversation.summary` ("о чём мы говорили") pulls the
  last 12 turns from persisted history, asks LLM for a 1-3 sentence
  recap in Jarvis tone. Falls back gracefully when offline.
- `conversation.repeat` ("повтори") re-speaks the last assistant message.
- New Lua API `jarvis.llm_history()` returns array of {role, content}
  tables, excluding the system prompt.

WOL pack (NEW `wol/`):
- Voice "разбуди сервер" / "wake server" fires a magic packet at a MAC
  stored in long-term memory under `wol_<alias>` (default alias "server").
- Setup via voice: "запомни wol_server AA:BB:CC:DD:EE:FF". Falls back to
  `JARVIS_WOL_TARGET` env if memory empty. Handles every standard MAC
  format (colons / dashes / dots / bare). Broadcast on UDP 9 via
  PowerShell System.Net.Sockets.UdpClient.

Outlook COM pack (NEW `outlook/`, via subagent):
- 4 commands: unread_count, latest, send_clipboard, summarize_inbox.
- PowerShell COM bridge `_outlook.ps1` with tab-delimited line protocol.
- summarize_inbox calls LLM for a one-paragraph summary. Graceful
  failure when Outlook isn't running.

Time tracker pack (NEW `time_tracker/`, via subagent):
- 5 commands: start, stop, today, week, reset.
- Persists via `jarvis.state` (structured object: current_session_start
  + sessions array of {start, end}).
- Local-calendar "today" boundary, full Russian pluralisation
  (час/часа/часов, минута/минуты/минут, сессия/сессии/сессий).

Tests: 139 rust (no regression), 81 python (60 → 81, +14 time_tracker
+7 outlook). Release build green for jarvis-app and jarvis-cli.

Pack count: 88 → 92 rust packs.
