Join: merge A3's builder and L3 (wip/registry-a3 88a9d19)

L3 (710c4032) arrives with it. Conflicts, each kept from both sides:
- assigner module.json, manifest_test.go, main.go, tools.go, integration_test.go: A2's first-view tools,
  read tools and states beside L3's assigner_engine_reads and engine-reads; the two "consumes" lists
  joined into one (the indexer's views and node-engine.manifest-reads-changed).
- builder module.json and manifest_test.go: A3's tools, states, consumes and invokes beside A2g's first
  views (DLV-M1); one findings state (A3's, history 5) carries both; reads keep A3o's
  mesh-delivery-indexer.packages until the builder follows it (join item).
- builder cmd main.go: rebuilt from A3's with A2g's changes applied (the reader follows modules,
  manifests, candidates and placement; one calls connection; one findings bucket, A3's
  health.FindingsBucket; FollowPlacement on a goroutine once placement's first view is answered;
  buildFromModules in place of the start's settle). Tools main.go: A3's tools then the first-view tools.
- builder run.go: A2k's out-of-step on the end entry, then A3's numbering of a done build.
- view module.json and manifest_test.go: node_manifest_reads and seat:node-engine.manifest-reads beside
  A2j's first views and read tools; one invokes list.
- indexer judge rules_test.go: L3's manifest-reads verb and event, without pull-waits (J1 dropped it).
- sdk/go.mod and builder go.mod: both requires kept.
