ProseForge Agent v0.4.0

General Agent Runtime release.

Added

• pf-agent is now positioned as a general personal Agent CLI Runtime with
  ProseForge Novel available as the first built-in workflow pack.
• The product TUI shows setup, provider/model, workspace, active workflow, and
  next actions instead of a novel-only or blank demo surface.
• pf-agent workflow list and pf-agent workflow use <name> expose the
  workflow pack model.
• pf-agent chat / pf-agent run now build a shared Agent Kernel with default
  tools, intent routing, session storage, injection safety, and project
  retrieval where a project is bound.
• ProjectChatRetriever provides deterministic project evidence retrieval from
  manifests, bible files, timelines, relations, foreshadowing notes, chapters,
  scene artifacts, and existing RAG chunks.

Changed

• pf-agent run now resolves the requested or configured provider instead of
  always constructing the fake provider. Real providers without keys return
  setup guidance instead of silently falling back.
• Offline runs explicitly require fake/local provider behavior and reject
  explicitly requested network providers.
• chat --show-citations now reports real project evidence refs when project
  files exist.
• Legacy TUI and REPL fallback paths now receive the same default tools,
  retrieval, session, and safety wiring as the main chat surface.

Fixed

• Intent router tool targets are now aligned with the default tool registry,
  including provider.configure.
• Missing tool registries now return a traceable error instead of crashing with
  a NoneType tool execution failure.
• Tool permission errors now show both required and current permission levels.
