feat: rename incident list --title to --query (#10)

The SDK's incident list API expanded its title filter into a
broader free-text query that also matches labels, content, and
resolves 24-char incident IDs / 6-char incident nums to direct
lookups. Rename the CLI flag to reflect the wider semantics.
