feat: Korean Chrome locale, agents/llm.md voice instructions, drop emoji rule

- run-chrome.sh: render web content (YouTube/Google/Naver) in Korean. --lang
  only sets Chrome's UI; the Accept-Language sent to sites comes from the
  profile's intl.accept_languages, which a persisted user-data-dir kept at
  en-US. Seed the profile to ko-KR and add --accept-lang=ko-KR,ko.
- agents/llm.md: runtime instructions for the reply LLM (loaded by the agents
  feature) — name "자비스", concise 1-2 sentence TTS replies (no emojis/markdown),
  nuance-based intent, and YouTube voice controls (open/search/play Nth/pause/
  back) via the on-screen browser tool.
- CLAUDE.md: drop the "use emojis in CLI output" rule — this assistant replies by
  Discord voice, not CLI, so output should be plain.

-All user-facing command line output should make use of emojis. Especially an initial emoji to start off the lines that depict what the line is about. Output should make use of indentation spacing to establish a visual hierarchy and aim to make output as easy to sift through as possible. Exception: Windows .bat scripts cannot use emojis (cmd.exe doesn't render Unicode properly).
+This assistant is used through a Discord bot with voice (TTS) replies, not a CLI. Do not add emojis to user-facing assistant output. Keep output plain and readable. (Runtime assistant behaviour lives in `agents/*.md`, which is injected into the reply LLM's prompt.)

   - Unified system prompt from [src/jarvis/system_prompt.py](src/jarvis/system_prompt.py) + ASR note + tool-protocol guidance. Reply language is resolved by `reply_language_directive(lang, cfg.tts_engine)` where `lang = _resolve_output_language()` — the single source of truth that prefers the settings-web UI value (config JSON `output_language`) over the compose `OUTPUT_LANGUAGE` env, so changing the language in the settings page takes effect. An explicit lock wins (forces "reply only in `<language>`", also forbidding other scripts so small models stop leaking trailing CJK/Hanja); else a Piper/Chatterbox TTS forces English (English-only voices); else (multilingual TTS, no lock) the assistant replies in the user's own language. The directive is inserted near the FRONT of the guidance list so a small model gives it primacy, and the SAME resolved `lang` feeds `build_system_prompt()`, which rewrites the persona's "in the user's language" clause to the locked language so the persona cannot contradict the directive (previously the persona read the raw env while the directive read the config value, so a settings-UI change was honoured by one and ignored by the other). Gated in `_build_initial_system_message()` at [engine.py](src/jarvis/reply/engine.py).
+  - **Operator instructions** (two sources, both framed "Additional instructions from the operator:" and appended near the end of the guidance list): the settings-UI `llm_instructions` config field, and every `*.md` file in `AGENTS_DIR` (default `/app/agents`, bind-mounted from `./agents`). The file-based set is read once per turn by `load_agent_instructions()` in [src/jarvis/system_prompt.py](src/jarvis/system_prompt.py) and concatenated in filename order, so dropping/editing a `.md` applies on the next reply with no rebuild/restart; fail-open to `""` when the folder is absent/empty/unreadable.
   - **Warm profile block** (query-agnostic User + Directives excerpt from the knowledge graph, composed by `build_warm_profile()` / `format_warm_profile_block()` in [src/jarvis/memory/graph_ops.py](src/jarvis/memory/graph_ops.py) at Step 3.5 of `reply()`; no LLM call, pure SQLite read; injected unconditionally so personalisation is the default; result cached in `DialogueMemory._hot_cache` under `DialogueMemory.WARM_PROFILE_CACHE_KEY` for the lifetime of the active conversation. Invalidated on `stop`, on new-conversation entry, AND on User/Directives graph mutations via the listener registered in [src/jarvis/daemon.py](src/jarvis/daemon.py) against `register_graph_mutation_listener` in [src/jarvis/memory/graph.py](src/jarvis/memory/graph.py); World-branch writes are ignored)
