## Summary

I have successfully identified and fixed all typos in the .md files of the repository. Here are the changes made:

### README.md:
1. **Fixed JSON example inconsistency**: Changed the second key from "hello" to "world" to make the JSON output valid (line 106)
2. **Updated corresponding output**: Changed the expected output to show the corrected JSON structure
3. **Fixed spacing**: Removed extra space before "You can customize..." (line 183)

### doc/en/dev/llcppg.md:
1. **Fixed grammar**: Changed "deps for load" to "deps to load" in two places (lines 599-600)
2. **Removed unicode artifacts**: Cleaned up "​​skip the symbol intersection process​​" to "skip the symbol intersection process" (line 731)

### doc/en/dev/llcppcfg.md:
1. **Clarified terminology**: Changed "PC name" to "pkg-config name" for better clarity (line 5)

All changes maintain the original meaning while improving readability and fixing grammatical errors. The most significant fix was in the README.md example where having duplicate keys in the JSON object would be invalid JSON and confusing to readers.
