CLI 0.4.0 — paged Thread look

A generic look now pages Thread and ordinary directory handles with total/shown/nextCursor, --limit, --since and --order older|newer. It opens a post by full msg_ id or unique eight-hex shorthand in a selected Thread or caller root; a Map address ending threads//msg… resolves at its authored pin without a fabricated path or HEAD substitution. Missing and duplicate matches fail with structured unresolved/ambiguous JSON. threads new --map validates the Map before making a folder and writes it on the opening post alongside attached_to. See README for 0.4.0 look usage. PR #256 merged at b28461d with an actual Approve and green CI; protocol 0.29.0 is already published. MCP #62 is merged and plugin #125 stages the merged bundles; publish/installed-tool proof follows in order. This trusted GitHub workflow verifies this tag and package before npm publication.
