fix(#123): remove $schema field and bump version to 0.5.1 (#124)

* fix(#123): marketplace.json の $schema フィールドを削除しバージョンを 0.5.1 に更新

Claude Code の marketplace validator が $schema を Unrecognized key として
reject し、plugin が settings 上 enabled でも runtime で disabled 扱いに
なり全 skill がロードされない問題を修正する。

合わせて plugin.json / pyproject.toml / uv.lock / CHANGELOG.md のバージョンを
0.5.1 に bump。autoUpdate 経由で既存 0.5.0 ユーザに fix を配布する。

Closes #123

* docs(#124): CHANGELOG 末尾の比較リンク定義を 0.5.1 用に更新

[unreleased] の比較 base を v0.5.0 → v0.5.1 に置換し、
[0.5.1]: compare/v0.5.0...v0.5.1 を新規追加。他バージョンの
比較リンク定義との一貫性を回復する。

+- Remove `$schema` field from `.claude-plugin/marketplace.json` to restore plugin skill loading (#123)
+  - Claude Code's marketplace validator rejected `$schema` as an Unrecognized key,
+    causing the runtime to treat the plugin as disabled even when enabled in settings
+  - This blocked all insight-blueprint skills (`analysis-design`, `analysis-framing`,
+    `catalog-register`, `premortem`, etc.) from loading into the available skills list
