improve(solve-issue): planner must locate repo and read code before planning

- planner procedure: locate repo (cwd/clone/create), read source files, reference actual code
- planner frontmatter: add repoPath as required field
- developer procedure: cd to repoPath, create branch, commit with issue ref
