Unsupported seed mode

Error message

Unsupported seed mode "${seedMode}". Expected one of: minimal, full.

What it means

Enum guard on the worktree seed mode option: only 'minimal' and 'full' seed modes are implemented, and an unrecognized value would silently fall through to wrong seeding behavior, so it is rejected up front.

Solutions

Use a supported seed mode: minimal or full.

Defensive patterns

Strategy: validation
