v2.66.0

Operator console — human gate in the pipeline, autonomous approve→run

• Human gate is now a pipeline stage. The Active pipeline renders the human gate as its own
  node, sitting immediately before the irreversible devops step, so operators always see where
  the rails are. It lights up "N awaiting signature" when gates are pending; clicking it jumps to
  the inbox where they get signed. (getPipeline() inserts the node; the board renders it.)
• approve→run defaults the agent prompt from the task body. "Approve + ▶run" now seeds the
  launch prompt from the task's own bd show (title + description + labels + a TDD/close
  instruction) instead of a generic string — the "ready-to-run prompt embedded in the issue"
  pattern. The operator still sees and edits the prompt before anything launches, so the human
  gate is preserved. New endpoint: GET /api/agent/prompt-for?id=<task>.

Security / hardening

• Invite links now expire. Operator invites carry a 7-day TTL by default
  (GREAT_CTO_INVITE_TTL_DAYS, 0 = never). resolveInvite/acceptInvite reject expired tokens
  and the Team panel lists them as expired — closing the "a leaked invite link is permanent"
  gap. +4 tests.
• POST body-size cap. The board now caps request bodies at 2 MB (413 + socket destroy) at a
  single point, guarding every route's body += c accumulation against unbounded buffering.

Tests

• pipeline-e2e updated for the new contract: 8 agent stages + 1 human-gate node, asserting
  the gate sits immediately before devops. Suite green (tests/lib 351/351).
