@zkochan @nachoaldamav Can we revert this PR? I don't think the pruneTree logic is correct. It's causing several correctness issues. In general, I think correctness is more important than memory usage.

• Transitive dependency linking back to workspace shows in pnpm why, but is not installed nor included in pnpm ls #7283
• pnpm list output is truncated from v.8.9.0 #7378
• pnpm why and pnpm list are not showing output for installed packages #6995
• "pnpm why" doesn't work properly #8100
