docs(plugin-dev): deprecate commands/ in favor of skills/<name>/SKILL.md (#717)

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.

+## Windows Compatibility
+
+The stop hook uses a bash script that requires Git for Windows to run properly.
+
+**Issue**: On Windows, the `bash` command may resolve to WSL bash (often misconfigured) instead of Git Bash, causing the hook to fail with errors like:
+- `wsl: Unknown key 'automount.crossDistro'`
+- `execvpe(/bin/bash) failed: No such file or directory`
+
+**Workaround**: Edit the cached plugin's `hooks/hooks.json` to use Git Bash explicitly:
+
+```json
+"command": "\"C:/Program Files/Git/bin/bash.exe\" ${CLAUDE_PLUGIN_ROOT}/hooks/stop-hook.sh"
+```
+
+**Location**: `~/.claude/plugins/cache/claude-plugins-official/ralph-wiggum/<hash>/hooks/hooks.json`
+
+**Note**: Use `Git/bin/bash.exe` (the wrapper with proper PATH), not `Git/usr/bin/bash.exe` (raw MinGW bash without utilities in PATH).
