forge v0.3.0 — plan/auto/manual modes + live message queue

Modes — shift+tab cycles (or /mode)

• auto — acts freely, no questions (the default, unchanged)
• plan — read-only: investigates with read/grep/glob/list, presents a plan via say; mutating actions are blocked with guidance
• manual — every mutating action (bash, write_file, edit_file, fleet_send) asks first:
  • y — yes, once
  • a — always: saves the approval (bash by command head like bash:git, others by action type) so it never asks again
  • n — no: the model is told not to retry as-is

Queue messages while it works

The input box stays live during a run — type and press Enter to deliver a message the agent absorbs between steps and steers by. Anything not absorbed becomes the next turn. The approval question paints in the activity row above the box.
