v0.11.1

Scopes the verifier gate so the routing cannot be read as contradicting Opus 5's guidance on self-verification. Docs only - no pin, config, hook, or stats changes.

• Scoped the verifier gate explicitly: the verifier gates ANOTHER agent's cheap-tier diff, never the main session's own work.
• Rationale: a current-generation model self-verifies, so spawning a subagent to re-check what the main session just wrote burns tokens for no quality gain - which is exactly what Opus 5's prompting guide means by "do not use subagents to verify or double-check your own work".
• Skill: the batched-output verifier bullet now carries that scope and the citation, alongside the existing "skip it when the main session reads the full diff anyway" exemption, so both ways of double-paying are named in one place.
• Routing anchor: the one-line verifier rule gained the same scope, so the distinction is present in every session rather than only on skill invoke.
• The cheap-tier gate itself is unchanged - gating another agent's diff was always the intent and stays recommended.
