Summary

fix: resolve #631 — autocomplete for variables inside structs

Problem

Severity: High | File: src/renderer/components/editor/fbd/FBDEditor.tsx

The FBD editor needs to be modified to provide autocomplete suggestions for variables inside structs and properly color them. The autocomplete system currently only suggests top-level variables but doesn't traverse into struct members. The syntax highlighting also incorrectly marks struct member variables as orange instead of white.

Solution

Changes

• src/renderer/components/editor/fbd/FBDEditor.tsx (new)
• src/renderer/components/editor/autocomplete/AutocompleteProvider.ts (new)
• src/renderer/components/editor/syntax/SyntaxHighlighter.ts (new)

Testing

• Existing tests pass
• Manual review completed
• No new warnings/errors introduced
