speccoder 0.6.0

Added

• Shape. A writing check as you type (no model) and ✦ Shape,
  which proposes testable words; code marks what it added and dropped,
  and you decide each before the words are used. speccoder shape,
  review edit --shape.
• Needs You by what it means: Blocked on you (oldest first), Ready
  to review (riskiest evidence first, its reasons as chips), Working,
  Idle — in the app and speccoder inbox (--json: groups,
  working, idle, risk).
• Approvals of one tool decided together: Approve N / Reject N…,
  speccoder task approve T1 T2 …; each still its own decision.
• A tick made by an external agent carries Executor: <preset>.

Changed

• Notifications only when something blocks work (a call waiting, a task
  that did not pass), named by the task's title. The sidebar and Dock
  badges count only Blocked on you.
• A parallel lane or bisection worktree starts with the feature
  worktree's target/ and Node folders cloned copy-on-write when the
  lockfile is the same (APFS, Btrfs, XFS): a Rust lane's first build went
  from 6.3 s to 0.2 s. .venv/ is never cloned.
• Built on agentplane 0.56.1.

Fixed

• An OpenAI model sending its structured answer as two messages no longer
  stops the task with ACCEPTANCE-UNWRITTEN (agentplane 0.56.1).
• An author's answer that cannot be used says why, in the provider's
  words, instead of generation did not succeed: failed.

Upgrading

• A finished feature and a stall no longer notify: add "feature_done",
  "stalled" to [ui.notify] on to keep them.
• speccoder replay of a run recorded before this release reports a
  divergence (model-call arguments are written differently).
