Release 0.5.0: agent plugins and localized install docs

Bump to 0.5.0, add a What's New entry (file + whatsnew command) for the
Claude Code / Codex plugins and the /harness-lint-capture command, and add
the Agent Plugins install section to the zh/ja/ko READMEs for parity.

+## Agent プラグイン（Claude Code と Codex）
+
+`AGENTS.md` に書いた静的な指示は一度しか読まれず、agent が実際に手を動かす瞬間からは遠い場所にあります。[`plugins/`](plugins/) のプラグインは代わりにライフサイクルフックを使い、セッションごとに Lint Driven Development のガイダンスを再注入し、プロンプトのたびに `harness-lint check --changed` を実行して**実際の現在の違反**を agent に渡し、次の行を書く前に修正させます。

+chmod +x .codex/hooks/*.sh
+```
+
+どちらも `/harness-lint-capture` コマンドを同梱しています。セッション中のフィードバックを見直し、再利用できる指摘をルールに落とし込みます（LDD のもう半分）。詳細は [`plugins/README.md`](plugins/README.md) と `~/.codex` のグローバル設定を参照してください。

+## Agent 플러그인 (Claude Code 및 Codex)
+
+`AGENTS.md`에 적은 정적 지시는 한 번만 읽히고, agent가 실제로 작업하는 순간과는 멀리 떨어져 있습니다. [`plugins/`](plugins/)의 플러그인은 대신 라이프사이클 훅을 사용해 세션마다 Lint Driven Development 지침을 다시 주입하고, 프롬프트마다 `harness-lint check --changed`를 실행해 **현재 실제 위반**을 agent에게 전달함으로써 다음 줄을 작성하기 전에 고치도록 합니다.

+
+둘 다 `/harness-lint-capture` 명령을 함께 제공합니다. 세션의 피드백을 검토해 재사용 가능한 지적을 규칙으로 정착시킵니다(LDD의 나머지 절반). 자세한 내용은 [`plugins/README.md`](plugins/README.md)와 `~/.codex` 전역 설정을 참고하세요.

+## Agent 插件（Claude Code 与 Codex）

+写进 `AGENTS.md` 的静态指令只会被读一次，且离 agent 真正动手很远。[`plugins/`](plugins/) 里的插件改用生命周期 hook：每次会话重新注入 Lint Driven Development 指引，并在每轮 prompt 前运行 `harness-lint check --changed`，把**当前实际违规**喂给 agent，让它在写下一行代码前就修复。

+## 0.5.0 — Agent plugins (Claude Code & Codex)
+
+**What it is.** Plugins in [`plugins/`](plugins/) that deliver harness-lint
+guidance through agent lifecycle hooks instead of a static `AGENTS.md` block:
+
+- **`SessionStart`** injects the Lint Driven Development working guidance plus any
+  diagnostics already present on changed files.
+- **`UserPromptSubmit`** runs `harness-lint check --changed` and injects the
+  current violations before the agent writes more code (silent when clean).
+- A manual **`/harness-lint-capture`** command reviews a session's feedback and
+  turns the reusable, GritQL-expressible corrections into rules.
+
+Both Claude Code and Codex use the same `hooks.json` schema; they differ only in
+install location. The hooks degrade gracefully when the `harness-lint` binary is
+absent.
+
+**Adopt it when:**
+
+- **Agents keep ignoring the harness-lint guidance you wrote into `AGENTS.md`.**
+  A hook re-injects it every session and surfaces live violations at the moment
+  the agent is about to act, which a one-time static block cannot.
+- **You want violations surfaced before code is written,** not only when the
+  human remembers to run `check`.
+
+**Do *not* adopt it for:**
+
+- **A repo where `AGENTS.md` guidance is already being followed.** The hooks add
+  a small amount of context to every prompt; if the static block works for you,
+  the plugin is redundant.
+- **Automatically inventing rules.** `/harness-lint-capture` is deliberately
+  manual — most turns produce nothing rule-worthy, so it is not wired to `Stop`.
+
+**Install.** Claude Code: `/plugin marketplace add CorrectRoadH/harness-lint`
+then `/plugin install harness-lint@harness-lint`. Codex: copy `plugins/codex/`
+into `.codex/`. See [`plugins/README.md`](plugins/README.md).
