v1.20.2 - prefer uv run invar

Highlights

• Pre-commit hook template now uses uv run invar guard instead of bare invar guard
• MCP setup documentation now recommends project-local uv run invar mcp as primary option
• All draft proposals and design docs updated to prefer uv run for invar commands

Included

• Pre-commit hook template: uv run invar guard / uv run invar guard --changed
• MCP setup guide: reorganized to recommend project-local first, uvx as fallback
• Design docs: installation examples updated to uv add --dev + uv run
• Draft proposals: CLI examples aligned with current recommended usage

Upgrade

uv tool install --force invar-tools@latest

For existing projects, run uv run invar init to regenerate the pre-commit hook with the new template.
