v3.9.4

Every progress message and the STATE.md cursor say which phase and which plan
a run is on, by position.

Added

• Progress messages name the phase and the plan by position. A line about
  one plan starts with "Phase N of M, plan K of J: ", where K is the
  plan's file number and J is the number of plans in the phase. /cad-execute
  prints it when it dispatches a plan, when the plan is done, and on every
  checkpoint, partial or risk line about that plan. /cad-plan ends with
  "Phase N of M: K plans written". The /cad-progress header and the
  /cad-context, /cad-pause and /cad-verify reports use the same words, and
  once every plan in a phase has run they name the phase alone. No position
  line counts tasks.
• STATE.md carries the plan position. cursor set writes an optional
  Plan: K of J (<plan name>) line after Phase:, naming the lowest-numbered
  plan whose report is not complete, and works it out from the plan files on
  every write. It writes no Plan: line when the phase has no plans or every
  plan is complete. /cad-execute rewrites the cursor after each plan, and
  after each batch on the parallel path. cursor get and status return the
  position as a plan field only when the line is there, so a four-line cursor
  written by an earlier Cadence reads back exactly as before. /cad-health
  checks the line's shape.
• Every new plan names itself in its heading. The PLAN template's heading
  is # Phase {N}: {phase name} - Plan {K}: {plan name}, and that name is what
  the progress messages print. A plan with no name in its heading prints as
  "plan K of J" with nothing after it.

Fixed

• /cad-config --review places OpenAI's current models. It left
  gpt-6-astra unclassified and put the Sol models in the flagship tier. Astra
  is now flagship, and Sol joins Terra in balanced.
