feat(modes): added /copy subcommands for flexible code and command extraction

- Added `/copy` command subcommands (code, all, cmd, last) for flexible code block and command copying.
- Added support for copying last executed bash or python command via `/copy cmd` subcommand.
- Refactored handleCopyCommand() to route subcommands with dedicated private methods for each copy operation.
- Added regex-based code block extraction from markdown with fallback warnings for missing blocks.
