Fix bin/ci-run-failed-specs to handle bare spec paths

The script previously only parsed spec paths in the format "rspec ./spec/..."
but failed on bare formats like "spec/system/integration_spec.rb[1:1:6:1:2]%"
which is what users might copy from shell output.

Changes:
- Add regex pattern to match bare spec paths (with or without ./ prefix)
- Strip trailing % characters from spec paths
- Normalize all paths to ./spec/ format for consistency
- Improve TTY detection to avoid spurious error messages
- Auto-confirm when TTY is unavailable instead of failing

Now supports all these input formats:
- spec/foo.rb[1:2:3]%
- ./spec/foo.rb[1:2:3]
- rspec ./spec/foo.rb[1:2:3]
