P0 follow-up for EA-471. Updates plugin-dev teaching materials to stop recommending the commands/ directory layout for new plugins: - command-development/SKILL.md: add legacy banner at top pointing to skills/ format - create-plugin.md: update scaffolding to create skills/<name>/SKILL.md instead of commands/; mark commands/ as acceptable legacy alternative; update all examples, tables, and testing instructions - example-plugin: migrate example-command to skills/example-command/SKILL.md; keep commands/example-command.md with a legacy-format note; update README to reflect new preferred structure Both formats remain loaded identically — this is a documentation change only.
