v0.1.5

Added

• dahrk service install / uninstall runs the node as a launchd or systemd user service, with no
  process manager and no root. (#22)
• An enforceable read_only stage policy denies every write and shell tool while still allowing
  Read, Grep and Glob. (#24)
• Interactive stages surface an agent's multiple-choice question as a Linear choice prompt with
  selectable options, one question at a time. (#25)

Changed

• The node advertises its resolved worktree base on connect, so a run's real worktree location is
  recorded in the hub's projection. (#23)
