Summary by cubic

Exclude the Neovim plugin lockfile from formatting and remove lockfile cleanup in the sync step to stop noisy diffs. Move treefmt configuration into flake.nix for consistent formatter command wiring, and enable zoxide Bash/Zsh integration.

• Bug Fixes

  • Exclude home-manager/programs/neovim/nvim-pack-lock.json from the JSON formatter.
  • Remove sed-based newline cleanup from neovim-sync in the Makefile.

• Refactors

  • Parse treefmt.toml in flake.nix and set formatter commands (nixfmt-rfc-style, biome, jsonfmt, shfmt); keep stylua, taplo, yamlfmt configured.
