fix: C++ generator bitfields, sizeof placement, Ctrl+F search, view sync

- Generator emits proper bitfield members instead of padding stubs
- Named bitfield structs (MitigationFlagsValues etc) now converted by parser
- sizeof comment moved from top to closing brace (}; // sizeof 0x80)
- C/C++ view syncs with workspace double-click and controller navigation
- Ctrl+F incremental search in C++ code view (Enter=next, Escape=close)
- Workspace dock resizable via 1px drag handle separator
- Regenerated Vergilius_25H2.rcx with all fixes (61 named bitfield containers)
