Plan: horizons, rank and appetite replace the endless backlog #204

The Work board shows every work item nobody is on as one Backlog column (up to 1,000 cards). g1t has no notion of order: there's no priority, rank or size, lists show the newest 100 with no paging, and nothing picks what comes next. This item replaces the pile with a short, ranked plan that people and agents both read from.

The model

• Horizon on every open item: triage → now → next → later → set_aside. Closed items have none. Each view is bounded: Now has a soft cap (6 by default, set per workspace, warns and never blocks), Next shows its top 10, Later is collapsed groups, Set aside is out of every view but search.
• Rank: a fractional index within a horizon. Position is priority, and there are no priority levels.
• Appetite: S (one session), M (a few sessions, about a week) or L (a phase, broken down before it moves to Now), with an optional spend budget.
• Urgent: a flag for fires. It sorts first in Now and clears when the item closes.
• Who can plan: anyone with write access triages and moves items within Next and Later. Moving into Now, or ranking Now, needs the same right as managing milestones.
• No cycles: Now is the commitment, and milestones carry the dates.

Phases

1. The plan exists. Horizon, rank, appetite and urgent on work items (migration, contracts, work service, a work_item.planned event, API, MCP plan/next, CLI g1t work plan / g1t work next). New items start in Triage. A Plan view at -/work with ranking. Docs.
2. Everything reads from it. The board becomes Now plus Up next. The list gets paging and sort. Home's Start here and dispatch pick from Next. Milestones become a filter on the plan.
3. Triage. g1t's AI suggests a horizon, an appetite and duplicates, and #203's drafts land here.
4. Progress draws itself. A derived hill per Now item, a "where it stands" summary, and a weekly digest.
5. Letting go. Later items untouched for 90 days go to Set aside.

Definition of done

• Phase 1 and 2 shipped (on main, deployed, documented), and #186–#203 placed in the approved order.
• g1t work next returns the top unblocked, unclaimed item in Next.
• No Work view shows more than its bound, at any size of workspace.
