Merge origin/master into goal-ui: adopt the rewritten client core and apiproxy carrier

Conflict rulings follow the projection-reattach plan:
- host/runtime package (deleted on master): take master; the PR's boot
  composition moves to the cordis.yml roster and its goals handlers will be
  re-landed in dsh-host-apiproxy; the session.prompt slash interception and
  its spec are dropped entirely (superseded by command.execute + command/run
  logging).
- client core (rewritten on master): take master; the PR's Session goal
  fields/methods, ConversationSnapshot.goal, goalActions injection, and the
  hard-mounted GoalBar are all superseded by the 'goal' session projection
  (useProjection) and will return as the ui-goal plugin.
- wire contract: union of master's workspace/command/skill domains and the
  PR's goal domain, minus goal.get (the read side is the projection block +
  session/projection frames; six mutation RPCs stay).
- GoalBar component and spec leave ui-conversation (they re-land in the new
  ui-goal package); IconSparkle16 stays in ui-conversation chat.
- The web-slash-command-dispatch note documents the dropped interception and
  is removed; the goal-bar note will be rewritten for the projection model.
- pnpm-lock.yaml taken from master (reinstall recomputes).
