Decide whether AgentV should become a component submodule

[smota]

Parent epic: #18

Goal

Decide whether to add AgentV as a components/ submodule after docs/templates prove useful.

Initial recommendation

Do not vendor AgentV source in phase 1. Start with toolsets/agentv/ docs/templates only.

If deeper integration becomes necessary, add components/agentv as:

• reference-only first, or
• tool-provider only if MetaSkills scripts intentionally call AgentV from submodule.

Acceptance criteria

• Decision recorded in docs or ADR.
• If submodule is added, include components/agentv.metaskills.md with mode and rationale.
• Native assets must not require reference-only component at install/runtime.
