docs: final cleanup - fix all remaining inconsistencies

Fixed:
- Badge URLs in README.md (cpfarhood → privilegedescalation)
- Repository references in docs/README.md
- Old version references in docs (v0.2.0 → v0.2.4)
- Tarball filenames in installation guides (0.2.0 → 0.2.4)
- Publishing documentation references
- Removed remaining emojis from README

All documentation now consistently references:
- Organization: privilegedescalation
- Version: 0.2.4
- No emojis or marketing fluff
- Correct tarball checksums
