Make execution options extend base options

- CompactExecutionOptions now extends CompactOptions
- ForkOptions (execution) now extends UserForkOptions (base)
- Moved UserForkOptions definition to workspaceFork.ts (source of truth)
- Pass options object directly to formatCompactCommand (no reconstruction)
- Eliminates field duplication and ensures type consistency
