gsd-capture

<objective> Capture ideas, tasks, notes, and seeds to their appropriate destination in the GSD system. Mode routing: - **default** (no flag): Capture as a structured todo for later work → add-todo workflow - **--note**: Zero-friction idea capture (append/list/promote) → note workflow - **--backlog**: Add an idea to the backlog parking lot (999.x numbering) → add-backlog workflow - **--seed**: Capture a forward-looking idea with trigger conditions → plant-seed workflow - **--list**: List pending todos and select one to work on → check-todos workflow - **--list-seeds**: List/audit captured seeds (optional status filter) → list-seeds workflow </objective> <routing> | Flag | Destination | Workflow | |------|-------------|----------| | (none) | Structured todo in .planning/todos/ | add-todo | | --note | Timestamped note file, list, or promote | note | | --backlog | ROADMAP.md backlog section (999.x) | add-backlog | | --seed | .planning/seeds/SEED-NNN-slug.md | plant-seed | | --list | Interactive todo browser + action router | check-todos | | --list-seeds | Read-only seed list/audit (optional status filter) | list-seeds | </routing> <execution_context> @~/.claude/gsd-core/workflows/add-todo.md @~/.claude/gsd-core/workflows/note.md @~/.claude/gsd-core/workflows/add-backlog.md @~/.claude/gsd-core/workflows/plant-seed.md @~/.claude/gsd-core/workflows/check-todos.md @~/.claude/gsd-core/workflows/list-seeds.md @~/.claude/gsd-core/references/ui-brand.md </execution_context> <contex...
