fix(archsetup): remove invalid --nodebug flag and add redshift configuration

Critical fix:
- Remove --nodebug flag from yay makepkg command (archsetup:375)
  * Flag is not supported in makepkg version on test VM
  * Was causing yay installation to fail with error code 3

Redshift configuration improvements:
- Add redshift package installation (archsetup:645)
- Fix redshift.conf dimness issues:
  * Increase gamma from 0.6 to 1.0 (neutral)
  * Increase brightness-day from 0.9 to 1.0 (full)
  * Increase brightness-night from 0.7 to 0.8 (less aggressive)
- Add redshift to .xinitrc startup services (line 62)
- Expand .xinitrc from minimal to full DWM session configuration

Additional cleanup:
- Remove obsolete startdwm script (replaced by full .xinitrc)
