feat(web): ui-goal package — GoalBar over the goal session projection

New client plugin package. The GoalBar component migrates verbatim from the
original PR (phase labels, inline edit form, resume-when-paused, pending
lockout, inline errors); its data path is rebuilt for the projection model:

- GoalDock adapter reads useProjection('goal') from the standard kit — no
  controller, no store, no refresh chain, no event listener (the original
  PR's Session goal fields, write-revision fence, and coalesced refetch all
  dissolve into the value store's seq rule).
- The inject face carries only the three mutation verbs; each reads the CAS
  ref from the session's current projected value at call time and maps the
  settled RPC result inline (callbacks from inject, live state from
  useProjection).
- Seats at conversation.input.dock order 1 (the slot contract names GoalBar
  as a resident of this strip), below TodoPanel/QueueDock, tucked against
  the composer; hero phase renders nothing for free.
- IconSparkle16 is package-local (sole consumer) — ui-primitives keeps only
  the shared action icons.
- goalbar.spec migrates with GoalSnapshot props (activation is process-local
  and absent from the projection; the strip renders durable phase only).
