v1.41.0

• Bring /stereo:quick to flag parity with the phase commands: --slot <name> targets a named
  durable plan slot with <slotArg> threaded onto all five slot-scoped companion invocations —
  including Quick's two plan-review launches, which store each parsed round durably and would
  otherwise overwrite the default slot under a Codex plan reviewer while the warning named the
  selected slot — with the existing-plan notice retargeted to the selected slot and deliberately
  kept warn-only
• Make both pause points configurable: --max-plan-rounds <n> (default 2, rejected above Quick's
  fixed absolute safeguard of 6) and --max-fix-rounds <n> (default 2), with cap-relative pause
  and keep-iterating wording in the command and README
• Add --isolated: implementation, implementation review, and fixes run in a throwaway detached
  worktree via the same machinery as /stereo:implement --isolated, minus durable state — Quick
  keeps no implementation record, so the worktree path is printed at creation and
  /stereo:doctor's stranded-worktree listing is the crash mitigation; the plan draft and plan
  review always run against the main tree, and the implemented marker is set only after an
  applied or empty patch
• Pin the new wiring structurally: the four flags in the argument hint, the <slotArg> idiom,
  both plan-review launch lines, and all four <isolationArgs> launch lines
