feat(v0.16): Anthropic plugin format + own marketplace

Makes KeiSeiKit installable both as classic kit AND as an Anthropic Claude Code plugin. .claude-plugin/plugin.json — plugin manifest (name, version, description, author OBJECT per schema, repository, license) .claude-plugin/marketplace.json — own marketplace declaration (owner OBJECT per schema, plugins[].source OBJECT) .claude-plugin/mcp-template.json — template for .mcp.json (actual .mcp.json write is blocked by hook; user copies template manually) PLUGIN.md — dual-install docs (plugin vs classic) hooks/hooks.json — uses ${CLAUDE_PLUGIN_ROOT} (per Anthropic schema, NOT ${PLUGIN_ROOT}); wraps hooks under top-level "hooks": {...} key Schema corrections caught during agent validation: - marketplace.json owner MUST be object (not string) - hooks.json requires "hooks": {...} top-level wrapper - env var is ${CLAUDE_PLUGIN_ROOT} not ${PLUGIN_ROOT} Companion edits in install-split bundle: install/lib-args.sh gains an 8-line plugin-first banner in print_help() directing users toward the plugin install path as recommended default. Dual-install strategy: users can pick - `claude plugin marketplace add <url>` then install — latest and iteration-friendly (this PR enables it) - classic ./install.sh — legacy kit path, full 37-primitive control Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

+# KeiSeiKit — Anthropic Claude Code plugin format
+
+This document describes the plugin-format install path (v0.16+) and how it relates to the classic `./install.sh` path. Both paths are supported; use whichever fits.
+
+## TL;DR
+
+```bash
+# One-time
+/plugin marketplace add KeiSei84/KeiSeiKit
+# Install
+/plugin install keisei@keisei-marketplace
+```
+
+The plugin auto-registers: agents, skills, hooks, and the MCP server. No manual `~/.claude/settings.json` edits. No `install.sh` needed for the core (non-primitive) experience.
+
+## Layout
+
+The repo follows the [Anthropic Claude Code plugin spec](https://code.claude.com/docs/en/plugins):
+
+```
+.claude-plugin/
+  plugin.json          # plugin manifest (name, version, author, license, keywords)
+  marketplace.json     # marketplace manifest — lets this repo serve as a marketplace source
+  mcp-template.json    # template for .mcp.json (copy to repo root; see "MCP prerequisite" below)
+agents/                # auto-discovered by Claude Code at plugin-install time
+skills/<name>/SKILL.md # auto-discovered
+hooks/hooks.json       # PreToolUse / PostToolUse / Stop hooks with ${CLAUDE_PLUGIN_ROOT} paths
+.mcp.json              # MCP server registration (see prerequisite note)
+```
+
+Paths inside `hooks/hooks.json` use `${CLAUDE_PLUGIN_ROOT}` (expanded by Claude Code at runtime to the plugin install directory) rather than absolute `$HOME/.claude/hooks/...` paths. This lets the same hooks ship unchanged whether the plugin is installed from GitHub, npm, or a local path.
+
+## Plugin install vs classic install — what differs
+
+| Feature | Plugin install | Classic `./install.sh` |
+|---|---|---|
+| Agents registered | yes, automatic | yes, copied to `~/.claude/agents/` |
+| Skills registered | yes, automatic | yes, copied to `~/.claude/skills/` |
+| Hooks wired | yes, via `hooks/hooks.json` | requires `--activate-hooks` (jq-merge of `settings-snippet.json`) |
+| MCP server | yes, via `.mcp.json` (once `@keisei/mcp-server` is published) | same |
+| 24 Rust primitives | **no** — plugin ships manifest sources only; no cargo build | yes, `--profile=<name>` builds the selected set |
+| 13 shell primitives | **no** | yes, copied to `~/.claude/agents/_primitives/` |
+| Disk footprint | ~2 MB (plugin cache) | ~2 MB minimal up to ~200 MB full |
+| Update path | `/plugin update keisei` | `git pull && ./install.sh` |
+| Update visibility | Claude Code shows version change | silent |
+
+**Bottom line:** plugin install is the right default for the agent-kit experience (agents + skills + hooks). For the Rust primitives (`tomd`, `kei-ledger`, `provision-hetzner`, `kei-migrate`, etc.), fall back to the classic installer or run it alongside the plugin — the two don't collide because the plugin namespaces into its own install dir and the classic installer writes to `~/.claude/`.
+
+## Prerequisites
+
+**For plugin install:**
+- Claude Code 2.1+ (check with `claude --version`)
+- Network access to `github.com/KeiSei84/KeiSeiKit` on `/plugin marketplace add`
+
+**For the MCP server subset:**
+- `@keisei/mcp-server` published to npm — **STATUS: not yet published as of v0.16.0.** The `.mcp.json` entry is structurally correct and will activate automatically once the package is published. Until then, the `keisei` MCP server simply won't appear in your tool list — the agents, skills, and hooks all work without it.
+- Node.js 18+ (for `npx` to fetch the server on demand)
+
+**For the Rust primitives (classic install only):**
+- Rust stable, `jq`, plus the soft-deps listed in the main README per-profile table.
+
+## Known limitations
+
+1. **Rust primitives not auto-installed.** The plugin format doesn't currently express "also run `cargo build` at install time". We ship the manifest sources in-repo so that users who want the primitives can run `./install.sh --profile=full` alongside the plugin. A future version may add pre-built release binaries for common platforms (macOS arm64/x86_64, Linux x86_64) into `bin/` so the plugin can ship primitives without a cargo step.
+2. **`@keisei/mcp-server` not yet on npm.** The `.mcp.json` entry is the canonical intent, but the package needs publishing first. See `_ts_packages/packages/mcp-server/README.md` for the publish pipeline.
+3. **Hooks use `${CLAUDE_PLUGIN_ROOT}`.** This is the official Claude Code plugin variable. Older Claude Code versions (<2.1) that predate plugin support will not expand this variable — stick with classic install on those versions.
+4. **No version-pinning yet.** `/plugin install keisei@keisei-marketplace` installs the default branch HEAD. For reproducible team installs, add the `--ref=<tag>` flag once it lands in Claude Code (currently in the spec per the extension schema `ref` field).
