feat: Evolver — official Claude Code plugin + evomap marketplace

GEP self-evolution for Claude Code: session hooks (memory inject / signal detect / outcome record), zero-dep MCP bridge to the EvoMap Proxy mailbox (genes & capsules), 7 slash commands, evolution-loop skill, strategist agent. Verified with 'claude plugin validate' and a real --plugin-dir load.

+# Changelog
+
+All notable changes to the Evolver Claude Code plugin are documented here.
+This project adheres to [Semantic Versioning](https://semver.org/).
+
+## [0.1.0] — 2026-06-04
+
+Initial release. Packages Evolver's Claude Code integration as an installable plugin.
+
+### Added
+- **Hooks** (`hooks/hooks.json` + bundled, dependency-free scripts):
+  - `SessionStart` → inject recent evolution outcomes as context.
+  - `PostToolUse` (Write/Edit/MultiEdit) → detect evolution signals in edits.
+  - `Stop` → record a git-diff-derived outcome to the EvoMap Hub or local memory.
+  - Evolution memory standardized under `~/.evolver/memory/evolution/memory_graph.jsonl` so the loop is self-contained (no dependence on the engine source tree).
+- **MCP bridge** `evolver-proxy` (zero-dependency stdio server): `evolver_status`, `evolver_search_assets`, `evolver_fetch_asset`, `evolver_publish_asset`, `evolver_poll`.
+- **Slash commands**: `/evolver:run`, `/evolver:solidify`, `/evolver:review`, `/evolver:sync`, `/evolver:distill`, `/evolver:search`, `/evolver:status`.
+- **Skill** `evolution-loop` (model-invoked) and **subagent** `evolution-strategist`.
+- `userConfig` for node id, hub URL, proxy port, and default strategy.
+
+### Notes
+- Active commands use a global `evolver` CLI when present and fall back to `npx -y @evomap/evolver`.
+- Compatible with `@evomap/evolver` ≥ 1.80.
