chore: migrate from opencode to trellis 0.5.0-rc.6

- Remove legacy .opencode/ directory and configuration - Update .trellis/ to v0.5.0-rc.6 structure - Refactor scripts: modularize common/, remove multi_agent/ - Add new common modules: git.py, io.py, log.py, types.py, etc. - Update workflow.md and AGENTS.md - Archive completed migration tasks

+The user-facing concept is a single "active task". Trellis stores that pointer
