- team-planex/planner: fix `ccw issue new` → `ccw issue create --data`, `solutions` → `solution`
- team-planex/executor: fix `in-progress` → `executing`, `resolved` → `completed`, `solutions` → `solution`
- commands/issue/convert-to-plan: fix `solutions --issue <id>` → `solution <id>`
- issue-manage SKILL: add solution/solutions endpoint documentation
- issue.ts help text: add missing `solutions` and `task` subcommand entries
