feat(v11): ship .claude-plugin/plugin.json — declare ACOS as Claude plugin

Was missing despite acos-meta SKILL.md referencing it as core to v11.
Manifest reflects current shipped state (10 skills) not aspirational
(90+ in ACOS_V11_MASTER_PLAN.md). Declares compose.extends = [creator-meta]
which lives at ~/.claude/skills/creator-meta/ as the abstract substrate.

Components:
- name, version (11.0.0), author, repo, license
- compose.extends: ["creator-meta"] — substrate inheritance
- compose.absorbs: knowledge-work-plugins, superpowers, oh-my-opencode, claude-flow
- stats: honest current counts vs aspirational targets
- intelligence: weighted score components from acos-meta SKILL.md
- principles: progressive disclosure, connector agnosticism, layer model
