majiayu000 Upgrade Flake Inputs
Update flake.lock to pull in the latest commits from all flake inputs. This gets you newer package versions without changing NixOS release channels.
What this does
- Updates all inputs to their latest commits (nixpkgs, home-manager, etc.)
- Does NOT change release channels (stays on same NixOS version)
- Safe operation - can always rollback

# Revert flake.lock to previous state
