Runrail 0.1.0

First public release.

• A local-first native task engine with workspace policy, approvals, budgets,
  verification and repair, sessions, checkpoints, forks, and handoffs.
• run checks each turn with a command you name, or an installed nifra check
  in a Nifra project; console, serve, and control check only when asked.
• In a Nifra project, Runrail's own loop gets the nifra mcp tools, and Pi gets
  Nifra's instructions and tools; other projects get neither. run and
  console say so, nifra.status reports it, and --no-nifra or
  RUNRAIL_NIFRA=off turns it all off.
• run and console save each session (--no-session to skip): --continue,
  --resume <id>, and --fork <id> pick one up on its saved backend and
  model; runrail sessions lists them and runrail export prints one as
  JSON or Markdown.
• runrail doctor checks Bun, git, the coding tools and their sign-ins, the
  key store, and the folders Runrail writes, with no network call.
• runrail new starts an app from a starter: Nifra (the default), Vite, Next.js,
  or an empty folder.
• One capability-routed boundary for native Runrail, Codex, Claude Code (the
  Agent SDK is fetched on first use, never shipped), Pi, ACP agents such as
  Copilot, and a PTY JSONL harness.
• First-party OpenAI, Anthropic, OpenAI-compatible, and xAI/Grok providers,
  with caller-owned slots for Google, Vertex AI, Bedrock, and llama.cpp.
• Bounded native tools, an MCP server, skills, integrity-checked plugins,
  workflows, and caller-owned GitHub, Linear, Jira, and Slack connectors.
• An authenticated loopback control RPC that the Runrail desktop app drives.
• Built on the public Nifra 5.3.0 packages. Licensed AGPL-3.0-only with a
  section 7 permission for Anthropic's Claude Agent SDK (see NOTICE).
