Click v0.96.0

Click v0.96.0 makes incremental verification more selective while keeping uncertainty conservative.

• Rejects shard layouts whose selected child plus management overhead is slower than the parent.
• Defers duplicate Evidence bootstrap child execution to the ordinary one-use baseline runner and supports bounded long-running setup checks.
• Adds owner-committed file-input policy v2 for child-specific cross-revision reuse, including ignored files and directory membership.
• Keeps stable bounded Vitest/Jest groups for inventories larger than 64 files.
• Shares one request-local Git preflight and records SIGTERM interruption without leaving a passing receipt.
• Adds paired equivalent-work evaluation that counts setup, failures, retries, and the final full audit.

Existing automatic sharding init/status/refresh, policy v1, complete inventory, authorized shard reuse, and conservative parent fallback remain supported.

The included short CLI fixture is intentionally reported as slower with Click. This release does not claim whole-agent, token, production, or tens-of-minutes savings.
