L/hud dev redesign

[lorenss-m]

Note

Adds live-trace dev flow with --new, a tasks-to-remote convert command, build/eval improvements, agent telemetry/naming changes, server CORS + REST response tweaks, and bumps to 0.4.55.

• CLI:
  • Dev UX: hud dev gains --new to create live traces via HUD API and show a minimal UI; Docker dev flow validates Docker and supports live trace; consistent UI tweaks.
  • New Command: hud convert converts local tasks to remote MCP format (uses lock, updates/preserves images, headers).
  • Build: Detects/merges env vars (incl. .env), warns for missing -e flags, writes required/optional vars, updates task files’ Mcp-Image/docker args to new version, and shows hud run <version_tag>.
  • Eval: Warns/confirms when tasks use local MCP (port conflict hint) with guidance to use hud convert.
• Agents:
  • Naming/Checkpoint: Standardize model_name (e.g., Claude, Operator, GenericOpenAI) and add checkpoint_name; Generic OpenAI uses checkpoint_name for API calls.
  • Telemetry: New utils to log agent metadata and compact task config to current trace.
  • Tests updated accordingly.
• Server:
  • Auto‑add CORS for HTTP/SSE; REST /api/tools/* now returns raw tool result JSON (no success wrapper).
• Telemetry/Settings:
  • _update_task_status_* accept extra_metadata; add HUD_API_URL setting.
• Client:
  • Environment analysis uses inputSchema key casing consistently.
• Release/Docs:
  • Bump version to 0.4.55 across code, tests, and docs.
