Description

Synchronize managed OpenCode agent colors with the active mode while preserving unrelated configuration, custom colors and semantic JSON fallback behavior.

Type of Change

• feat: new feature

Checklist

• Focused38 agent-color cases pass, including malformed/duplicate/custom inputs, idempotence and public sync integration.
• Full exact-candidate pytest, Ruff, mypy, links, health and preview pass through normal hooks.
• Tests accompany the shared sync behavior; no attribution trailers.

Independent final source snapshot:1119 Python tests,86.47% coverage, links/health PASS. Full isolated Bats138/140 initially failed because HOME hid jsonschema; existing-venv PATH correction gave focusedroute12/12 PASS, no source fix. This exact head requires hosted CI. No live provider/config activation claimed. RDD disabled/unmanaged.
