Standpoint 0.4.0 — multi-surface

Standpoint 0.4.0 completes the AI Helpers surface set: the same positioning()
engine — turn a comparison table into a labelled 2D positioning map + written analysis —
now reachable six ways, with nothing reimplemented across them.

Six surfaces, one engine

Library · CLI ×2 (standpoint argparse + standpoint-click) · GUI (standpoint-gui) ·
HTTP API (POST /api/position) · MCP (standpoint-mcp, tools at /mcp) · Claude/OpenCode skill.

Added

• MCP ([mcp] extra): fastapi-mcp publishes the FastAPI endpoints as MCP tools.
• Skill (skills/standpoint/): trigger-rich SKILL.md + references/ + a
  positioning_summary.py helper; exhaustive TRIGGERS.md referenced from the READMEs.
• Docker (installs requirements.txt, serves API + MCP) + .dockerignore; a thin
  conda environment.yaml; a fuller requirements-dev.txt.
• Prompts moved to standpoint/locales/i18n.yaml (en/fr/es).

Install: pip install standpoint (core) · "standpoint[gui]" · "standpoint[mcp]".
