feat: enum/bitfield editing, MCP guard rails, PDB anonymous type inlining

- Enum inline editing: name/value commit handling, auto-sort by value
- Bitfield support in PDB import with proper container nodes
- Per-member hover/selection highlighting (kMemberBit encoding)
- Context menu fixes for enum/bitfield member lines
- MCP pagination (limit/offset), includeMembers param, tree.search tool
- MCP status bar activity indicator for tool calls
- PDB anonymous type inlining: inline <unnamed-tag> types as children
- Skip anonymous pointer targets to prevent root orphans
- Enum import diagnostics for debugging missing enums
