fix(commands): wire dispatch files to real sub-command names via Skill tool

All dispatch files referenced display names (e.g., `/doc audit`) that don't
correspond to real slash commands. Claude Code resolves commands by filename,
so `/doc audit` loads `doc.md` with $ARGUMENTS but never routes to `doc-audit.md`.

Changes:
- Updated 24 dispatch files with explicit Skill tool routing
- Added "Command to Invoke" column with plugin-prefixed names
- Added $ARGUMENTS matching for automatic routing
- RFC dispatch file uses inline handling (no separate command files)
- Updated COMMANDS-CHEATSHEET.md with invocation methods
- Updated MIGRATION-v9.md with command name mapping explanation

Affects: 25 dispatch files across 12 plugins (core, data, saas, ops, debug)

-## Workflow
+## Routing
 
-1. Display the table above
-2. Ask: "Which command would you like to run?"
-3. Route to the selected sub-command
+If `$ARGUMENTS` is provided (e.g., user typed `/api scaffold`):
+1. Match the first word of `$ARGUMENTS` against the **Action** column above
+2. **Invoke the corresponding command** from the "Command to Invoke" column using the Skill tool
+3. Pass any remaining arguments to the invoked command
+
+If no arguments provided:
+1. Display the Available Commands table
+2. Ask: "Which action would you like to run?"
+3. When the user responds, invoke the matching command using the Skill tool
+
+**Note:** Commands can also be invoked directly using their plugin-prefixed names (e.g., `/saas-api-platform:api-scaffold`)
