docket 0.20.0

Added

• docket list --where and docket graph --where take a query language: plain words, kind:, state:, scope:PATH, is:pinned|corrected|retired|blocked, author:, branch:, after:, and before:, with - to negate a term. docs/commands.md lists the rules.
• The graph viewer filters with the same language. It previews text terms as you type and asks the CLI about field terms when you press Enter. A bottom pane shows the filter, the match count, the sort, and the key hints, and ? opens a help overlay.

Changed

• The graph viewer's / searches the id, text, choice, and rationale, and ANDs its words. Before, it matched one substring across every field. The LEDGER GRAPH title and the separate search line are gone.
