feat(commands): tier-1 PC tools — window mgmt, clipboard, notes, process killer, web search

Five new portable Lua command packs. Bumps the total from 11 to 16 packs.
All sandbox=full, all dispatched via jarvis.system.exec or jarvis.fs / jarvis.system
APIs, no new Rust code, post_build.py --sync copies them under target/.
cargo test -p jarvis-core --lib commands::tests passes 3/3 against all 16.

window/ — 8 commands, single dispatch.lua keyed by jarvis.context.command_id:
  show_desktop / maximize_window / minimize_window / snap_left / snap_right
  / close_window / restore_all / task_view. _window_helper.ps1 P/Invokes
  user32!keybd_event for arbitrary combos like "win+d", "alt+f4",
  "win+shift+m". Uses one shared script per pack — much less duplication
  than the volume/ approach.

clipboard_read/ — read_clipboard. Pulls jarvis.system.clipboard.get(),
caps preview at 400 chars, then shells PowerShell System.Speech to actually
speak it aloud (auto-picks the first ru-RU voice if present). Also fires a
notify with a 120-char snippet.

notes/ — add_note + open_notes. add_note strips the trigger phrase from
the recognized voice, appends "[YYYY-MM-DD HH:MM] body\n" to
%USERPROFILE%\Documents\jarvis-notes.txt via jarvis.fs.append (creates
the file on first call). open_notes opens the file in the default editor
via jarvis.system.open. Trigger list covers RU/EN/UA variants of
"запиши" / "запомни" / "write down" / etc.

process_kill/ — kill_process. Trigger-strips "закрой программу" / "убей
процесс" / etc., then runs the remainder through an alias map (хром→
chrome, телега→telegram, спотифай→spotify, edge/edge/едж→msedge etc.,
20+ entries) before invoking taskkill /F /IM. Notifies success/not-found.

websearch/ — search_google / search_youtube / search_wiki / search_yandex.
Single dispatch.lua reads jarvis.context.command_id to pick the base URL,
URL-encodes the query (Lua %02X gsub, not relying on jarvis.http), opens
the resulting link via jarvis.system.open (system default browser).

Portability check: every helper resolves paths via $env:USERPROFILE /
jarvis.context.command_path / jarvis.system.env — no hardcoded C:\ refs.
