DEFINITIVE tab character fix using hex dump analysis

Based on the GitHub Actions hex dump output, I identified the exact issues:

1. Line 395 in setup-local-dev.sh had tab at position 42
2. Lines 79,85,96,107,297,300,318,324 in test-kind.sh had tabs and Unicode chars
3. Unicode sequences (342 234 223, 342 234 227) were causing additional issues

Solutions applied:
- Downloaded actual GitHub versions of files (not local cached versions)
- Completely replaced every problematic line with clean ASCII-only versions
- Applied aggressive Unicode and tab cleaning to all other lines
- Verified with local lint check (now passes)

The hex dump debugging in the Makefile revealed the exact character positions,
enabling this precise fix. This should finally resolve the persistent issue.
