chore: CI workflows + drop Ukrainian (UA → just RU/EN)

CI (.github/workflows/ci.yml):
- Three parallel jobs on push & PR: cargo test (jarvis-core), cargo
  clippy (lint, warnings-as-errors), cargo check (workspace). Windows
  runner, stable toolchain, rust-cache for fast incremental builds.
- Deliberately skips release build of jarvis-gui — that needs Node+npm
  +Tauri bundler and would balloon CI to ~10min per push.

Drop Ukrainian:
- Delete ua.ftl, remove UA from SUPPORTED_LANGUAGES.
- config.rs: prune UA arms from get_wake_phrases / get_wake_grammar /
  get_phrases_to_remove / get_llm_trigger_phrases / get_llm_system_prompt.
- stt/vosk.rs: drop UA → uk language mapping.
- tray menu: drop "Українська" entry.
- frontend: drop UA from Header.svelte language list, settings page
  language map, i18n.ts fallback.
- 82 command.toml files stripped of every `ua = [...]` block (205
  blocks total). Handled via subagent — TOML still parses, all 6 command
  tests pass.

.gitignore: stop tracking dev.env / dll_probe*.py / imports_full.txt
which were sitting in working tree.

Tests: 128 pass (no regression). Workspace still compiles end-to-end.
